Answer:
length=(3x-2)
Step-by-step explanation:
area of rectangle=length*breadth
3x^2 + 7x - 6=length * (x+3)
3x^2 +(9-2)x -6=length *(x+3)
3x^2+9x-2x-6=length*(x+3)
3x(x+3)-2(x+3)=length*(x+3)
(x+3)(3x-2)=length*(x+3)
(x+3)(3x-2)/(x+3)=length
(3x-2)=length
Answer:
(3x - 2)
Step-by-step explanation:
Given that the area A = length × width
A = 3x² + 7x - 6 ← factor to obtain length
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 6 = - 18 and sum = + 7
The factors are + 9 and - 2
Use these factors to split the x- term
3x² + 9x - 2x - 6 ( factor the first/second and third/fourth terms )
= 3x(x + 3) - 2(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 2)
We know (x + 3) is the width , then (3x - 2) is the length

Two brothers are sharing a certain sum of money in the ratio 2/3 : 3/5, if the largest share was Gh¢500.00. How much was shared between them?
Given:
Two brothers are sharing a certain sum of money in the ratio [tex]\dfrac{2}{3}:\dfrac{3}{5}[/tex].
The largest share was Gh¢500.00.
To find:
The total amount shared between them.
Solution:
It is given that, two brothers are sharing a certain sum of money in the ratio [tex]\dfrac{2}{3}:\dfrac{3}{5}[/tex].
First we need to make the denominators common.
[tex]Ratio=\dfrac{2\times 5}{3\times 5}:\dfrac{3\times 3}{5\times 3}[/tex]
[tex]Ratio=\dfrac{10}{15}:\dfrac{9}{15}[/tex]
[tex]Ratio=10:9[/tex]
So, the two brothers are sharing a certain sum of money in the ratio 10:9.
Let the shares of two brothers are 10x and 9x respectively. So, the larger share is 10x.
It is given that the largest share was Gh¢500.00.
[tex]10x=500[/tex]
[tex]x=\dfrac{500}{10}[/tex]
[tex]x=50[/tex]
Now, the total amount shared between them is:
[tex]Total=10x+9x[/tex]
[tex]Total=19x[/tex]
[tex]Total=19(50)[/tex]
[tex]Total=950[/tex]
Therefore, the total amount shared between them is Gh¢950.00.

12 less than a number is equal to the product of 7 and that number. Convert into an
equation and find the number?
Answer:
EQUATION: X - 12 = 7X. SOLUTION: X = - 2.
Step-by-step explanation:
First, we do not know the number. When the number is unknown, it is a variable. I chose the variable, "X."
12 less than signals that we subtract 12. So that would be X - 12.
A product of 7 AND that number means we multiply 7 by X. That can be notated as 7X.
12 less than X is EQUAL to the product of 7 and X. So X - 12 = 7X.
To find the solution, we want to know the value of X. Move X to one side of the equation.
X - 12 = 7X
-X -X
_________
-12 = 6X
Divide both sides by 6 to get X by itself.
X = - 2.

Answer:
39.28cm^2
Step-by-step explanation:
Simple work out the area of a circle and halve it.
3.142xr^2
3.142x5^2 = 78.55 cm^2 (Full circle area)
Now we must halve that answer to get the semicircle.
78.55/2 = 39.275 cm^2
However, we need it to 2dp. Therefore the answer is 39.28cm^2
The picture is above I’ll mark as brainliest.
Answer:
Width = 3 m
Step-by-step explanation:
Formula for perimeter:
P = l + w + l + w
Plug in what we know:
14 = 4 + w + 4 + w
Isolate variable w (width):
14 = 8 + 2w
6 = 2w
3 = w
Check your work:
14 = 4 + 3 + 4 + 3
14 = 7 + 7
14 = 14

Step-by-step explanation:
To find the rainfall during the month of April simply multiply the number of days in April times the average daily rainfall
Number of days in April: 30
Average daily rainfall: 3.5mm
Rainfall during the month = 30 * 3.5 = 105mm
John invested $30000 in the bank for 4 years. At the end of the period, he had
$42520. Calculate
a. the interest earned
b. the rate per annum at which simple interest was earned to 1 decimal place.
Answer:
Rate = 10.4%
Step-by-step explanation:
Given :
P = $30000
A = $42520
Interest earned = 42520 - 30000 = $12520
Time = 4years
Find R
[tex]Interest = \frac{PRT}{100}[/tex]
[tex]12520 = \frac{30000 \times R \times 4}{100}\\\\12520 = 300 \times 4 \times R\\\\12520 = 1200 \times R\\\\R = \frac{12520}{1200}\\\\R = 10.43 \%[/tex]
Round to 1 decimal place, Rate = 10.4%

Jada makes sparkling juice by mixing 2 cups of
sparkling water with every 6 cups of apple juice.
A. How much apple juice does Jada need if she uses 6
cups of sparkling water?
B. How much sparkling water does jada need if she uses 15 cups of apple juice.
Answer:
A=36
B= 2.5
Step-by-step explanation:
If you need 1 cup of sparkling water per 6 cups of apple juice and you use 6 cups of sparking water you do 6x6=36
15 divided by 6 = 2.5
Answer:
A - 18. B - 5
Step-by-step explanation:
So, the best thing for us to do first is find the ration between apple juice and sparkling water.
Then we can answer the questions once we know the ratio.
We know that for every 6 apple juice, we need 2 sparkling water.
This is a 6 : 2 ratio.
However, we can simplfy this further by dividing the 6 and 2 by using a number that goes into both values, such as 2:
6/2 : 2/2
=
3 : 1
So this is our ratio.
Now, the first questino asks how many apple juice is needed for 6 cups of sparkling water?
We know 3 apple juce is needed for 1 sparkling water, so to find whats needed for 6, lets multiply the 3 by 6:
3*6
=
18
So we need 18 apple juice for 6 sparkling water.
Next we need to find how much sparkling water is needed for 15 cups of apple juice.
We know that for every 3 apple juice we need 1 sparkling water.
We gace 15 apple juice.
To find how much sparkling water we need, lets divide the amount of apple juice by the ratio of apple juice. This will get us how many times more sparkling water we need:
15/3
=
5
Now that we know how many times more sparkling water we need, lets multiply the sparkling water by this:
5*1
=
5
So we need 5 sparkling water for every 15 cups of apple jiuce.

Substituting these values;
7C3 = 7!/(7-3)! 3! = 7!/4!3! = 35

In a right triangle, sin(40 - 2) = cos(32)'. What is the value of x?
O 10
O 15
O 20
O 25
Answer:
x = 25
Step-by-step explanation:
Correct question
In a right triangle Sin (40-x)=cos(3x) what is the value of x
Since Sin theta = Cos(90-theta)
Sin (40-x) = Sin(90-3x)
40 - x = 90 - 3x
-x+3x = 90 - 40
2x = 50
x = 25
Hence the value of x is 25
A square is inscribed in an equilateral triangle that is inscribed in a circle.
A square is inscribed in an equilateral triangle that is inscribed in a circle. The square and circle are shaded.
Which represents the area of the shaded region?
area of the circle – area of the square – area of the triangle
area of the triangle – area of the square + area of the circle
area of the triangle + area of the square + area of the circle
area of the circle – area of the triangle + area of the square
The area of the shaded region is (area of the circle) - (area of the square) - (area of the triangle)
Option A is the correct answer
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The shaded region consists of the area inside the circle but outside the square, as well as the area inside the equilateral triangle but outside the square.
Now,
The area of the circle is πr²
Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square.
Let's say the side length of the square is s.
By the Pythagorean theorem,
s² + s² = (diameter)²
2s² = (2r)²
s² = r²
The area of the square is s² = r².
The area of an equilateral triangle with side length s is √(3)/4 x s².
Since the side length of the square is equal to the height of the equilateral triangle, the side length of the equilateral triangle is also equal to s.
The area of the shaded region.
= (area of the circle) - (area of the square) - (area of the triangle)
Thus,
The area of the shaded region is (area of the circle) - (area of the square) - (area of the triangle)

Answer:
(2ac+1)/(abc+2c+1)
Step-by-step explanation:
It helps to understand the factoring of the numbers involved.
63 = 3²·7
140 = 2²·5·7
The "change of base" formula is also useful.
[tex]\log_b{a}=\dfrac{\log{a}}{\log{b}}[/tex]
__
Using this, we can write ...
a = log(3)/log(2) ⇒ log(3) = a·log(2)
b = log(5)/log(3) ⇒ log(5) = b·log(3) = ab·log(2)
c = log(2)/log(7) ⇒ log(2) = c·log(7)
This lets us write everything in terms of log(7):
log(2) = c·log(7)
log(3) = ac·log(7)
log(5) = abc·log(7)
__
The desired logarithm is ...
[tex]\log_{140}{}63=\dfrac{\log{63}}{\log{140}}=\dfrac{2\log{(3)}+\log{(7)}}{2\log{(2)}+\log{(5)}+\log{(7)}}\\\\=\dfrac{2ac\cdot\log{(7)}+\log{(7)}}{2c\cdot\log{(7)}+abc\cdot\log{(7)}+\log{(7)}}\\\\\boxed{\log_{140}{63}=\dfrac{2ac+1}{abc+2c+1}}[/tex]
