To complete the square
add ( half the coefficient of the x- term )² to x² + 6x
x² + 6x + (3)²
= x² + 6x + 9

A.) 18.7 units
B.) 10.5 units
C.) 9 units
D.) 13 units
Answer:
B.) 10.5
Step-by-step explanation:
Use ratios, but be careful.
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or
[tex]\dfrac{a}{b}[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Using ratios;
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
Thus, option B.) 10.5 units is correct.

A ladder rests 22 feet up the side of a building. If the base of the ladder is 20 feet away from the building, how tall is the ladder to the nearest hundredth?
Answer:
Length of ladder =L =15
Distance from wall = D =9
Height on wall = H =??
Pythagoras equation L*L = D*D + H*H
15×15= (9×9) + H×H
225-81 = 144 =HxH
H= 12 feet.

Answer: 32768 or [tex]8^5[/tex].
Step-by-step explanation:
[tex]8^7[/tex]= 8x8x8x8x8x8x8 = 2097152
[tex]8^2[/tex]= 8x8 = 64
Dividing Exponents
When you divide exponents with the same base. You subtract. So in this case, you subtract 7 by 2, (being exponents). The same base is 8. So your subtracting [tex]8^7[/tex] by [tex]8^2[/tex]. Which will get you [tex]8^5[/tex].
Dividing Whole Numbers.
You are going to divide whole numbers. Its pretty self explanatory but I will do the math for you anyways.
64 goes into 2097152, 32768 times. Or we can say,
2097152 divided by 64 = 32768.
So the answer is 32768, or [tex]8^5[/tex].

Linda needs to have her car towed. Little Town Auto charges a flat fee of $75 plus $2 per miletowed. Write a function expressing Linda's towing cost, C, in terms of miles towed, x. Find thecost of having a car towed 14 miles.
The cost of having a car towed 14 miles is $103.
To express Linda's towing cost, C, in terms of miles towed, x, we can use the given information that Little Town Auto charges a flat fee of $75 plus $2 per mile towed.
The function for the towing cost, C, can be written as:
C(x) = 75 + 2x
Where x represents the number of miles towed.
To find the cost of having a car towed 14 miles, we substitute x = 14 into the function:
C(14) = 75 + 2(14)
C(14) = 75 + 28
C(14) = 103
Therefore, the cost of having a car towed 14 miles is $103.

Step-by-step explanation:
An architect draws a plan for a wheelchair ramp on the plan, the ramp is 2cm high and 24cm long what might the dimensions of the actual ramp be (use equivalent ratios)
Answer:
[tex]Height = 30cm[/tex]
[tex]Length = 360cm[/tex]
Step-by-step explanation:
Given
Scale Measurement
[tex]Height = 2cm[/tex]
[tex]Length = 24cm[/tex]
Required
Determine the possible actual measurement
First, calculate the equivalent ratio.
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{24cm}{2cm}[/tex]
[tex]Ratio = 12[/tex]
To do this, we pick a scale factor.
Assume the scale factor is 15.
The actual measurement will be:
[tex]Height = 2cm * 15[/tex]
[tex]Height = 30cm[/tex]
[tex]Length = 24cm * 15[/tex]
[tex]Length = 360cm[/tex]
When the scale ratio is calculated, we have:
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{360cm}{30cm}[/tex]
[tex]Ratio = 12[/tex]
Note that both have the same equivalent ratios of 12.
So, whatever the scale ratio you use, the equivalent ratio will be the same
You spend 264 dollars on clothes. Shirts cost 24 and pants cost :2 you buy a total of 9 items
EQUATIONS:
24x + 32y = 264
x + y = 9
x is shirts, y is pants
SOLVING by substitution:
x = 9 - y
24(9 - y) + 32y = 264
216 - 24y + 32y = 264
8y = 48
y = 6
x + 6 = 9

Find the value of x.
Answer:
-5
Step-by-step explanation:
Distribute 4(x+6) = 4x+6
Since the angle are congruent to eachother set them equal to oneanother
4x+6 = 5x+11
Subtract 4x on both sides.
6 = x+11
Subtract 11 on both sides.

For this equation: a=3, b=9, c=4
3x2+9x+4=0
Step 1: Use quadratic formula with a=3, b=9, c=4.
x=−b±√b2−4ac/2a
x=−(9)±√(9)2−4(3)(4)/2(3)

O salário de um artista é calculado através da função y = 2000 + 500x onde Y representa o valor total em Reais recebido em um mês de trabalho e "x" o número de shows realizados no mês. Qual foi o salário desse artista no mês em que realizou 12 shows?
Answer:
The artist's salary in the month is 8000.
Step-by-step explanation:
The salary of an artist is given by the function :
y = 2000 + 500x ....(1)
where Y represents the total amount in Reais received in a month of work and "x" the number of shows performed in the month.
We need to find the artist's salary in the month she performed 12 shows.
Put x = 12 in equation (1)
y = 2000 + 500(12)
= 2000 + 6000
= 8000
Hence, the artist's salary in the month is 8000.

Mark tried to pour 36 ounces of tea into 3 cups. after filling the cup to the top, there were still 13.5 ounces left in his tea pot. if each cup is the same size how much is in the tea cup? HELP PLEASE!
Answer:
its 12
Step-by-step explanation:
12 oz
Answer:
22.5/3
Step-by-step explanation:
Hey, the idea is to set up an equation that you can solve
36 ounces of tea = 3 cups(some ounces of tea) + 13.5 ounces left
Now just solve for how much tea is in each cup.
36-13.5 = 3(X)
3X = 22.5
x = 22.5/3
