Fencing required to go around the whole garden = 368 feet
To calculate the fencing needed, given measures in the question,
Total area of the garden is 4864 square feet.Length of the garden is 152 feet.Since, area of a rectangular garden is given by the expression,
Area = Length × Width
4864 = 152 × Width
Width = [tex]\frac{4864}{152}[/tex]
= 32 feet
Since, length of the fence needed = Perimeter of the garden
And Perimeter of a rectangular garden is given by the expression,
Perimeter = 2(length + width)
By substituting the values of length and width of the garden in the expression,
Perimeter = 2(152 + 32)
= 368 feet
Therefore, 368 feet of the fence will be required to go around the whole garden.

Find f(-2) for f(x) = 2•3^x
Answer:
2/9
Step-by-step explanation:
f(x) = 2•3^x
Let x = -2
f(-2) = 2•3^-2
We know that a^-b = 1/a^b
f(-2) = 2• 1/3^2
= 2/9
f(x) = 2 * 3^x
f(-2) = 2 * 3^-2
f(-2) = 2 * 1/3^2
f(-2) = 2 * 1/9
f(-2) = 2/9

Answer:
is it 6 with the 10
Step-by-step explanation:
Answer:
y = 6/5 x + 2/3
Step-by-step explanation:
A equation is given to us and we need to express it in , mx + b form . The given equation to us is,
[tex]\rm\implies 6 = \dfrac{15y - 10}{3x} [/tex]
Move 3x to LHS , we will get ,

y=x²+4x-3 y=5x+3 solve the simultaneous equation
Answer:
(-2, -7) or (3, 18)
Step-by-step explanation:
Start with your 2 equations
y = x^2 + 4x - 3
y = 5x + 3
Because both equal y, we substitute:
x^2 +4x -3 = 5x+ 3
x^2 - x - 6 = 0
Factor:
(x + 2) (x - 3) = 0
Solutions for x: -2 or 3 since if either of the numbers in parentheses is 0, the equation is 0 (0* anything = 0).
Then plug -2 in for x in either equation:
y = 5* -2 + 3
y = -7
So ( -2, -7) is a solution.
Plug 3 in for x in either equation:
y = 5*3 + 3
y = 18
So ( 3 , 18) is a solution.
Hope that helps, let me know if I did anything wrong!
Answer:
(- 2, - 7 ) and (3, 18 )
Step-by-step explanation:
Given the 2 equations
y = x² + 4x - 3 → (1)
y = 5x + 3 → (2)
Substitute y = x² + 4x - 3 into (2)
x² + 4x - 3 = 5x + 3 ( subtract 5x + 3 from both sides )
x² - x - 6 = 0 ← in standard form
(x - 3)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 3 = 0 ⇒ x = 3
Substitute these values into (2) for corresponding values of y
x = - 2 : y = 5(- 2) + 3 = - 10 + 3 = - 7 ⇒ (- 2, - 7 )
x = 3 : y = 5(3) + 3 = 15 + 3 = 18 ⇒ (3, 18 )
The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?
Answer:
10%
Step-by-step explanation:
The percentage decrease in price = [tex]\frac{decrease amount}{original amount}[/tex] x 100%
Original amount = 250,000
New amount = 225,000
Decrease in amount = 250,000 - 225,000
= 25,000
So that;
Percentage decrease in price = [tex]\frac{25000}{250000}[/tex] x 100%
= 0.1 x 100%
Percentage decrease in price = 10%
The price of the apartment dropped by 10% of its original price.

Answer:rrrrrrrr
rrrrrrrrrr
Step-by-step explanation:
rrrrrrrrrrrrrrr
The equation for the scenario is x + x+1 + x+2 = 117 and largest number is 40.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x be the first number:
The other numbers are:
x+1, x+2
The sum of three consecutive numbers is 117:
x + x+1 + x+2 = 117
3x + 3 = 117
3x = 114
x = 38
x+ 1 = 38+1 = 39
x+2 = 38+2 = 40
Thus, the equation for the scenario is x + x+1 + x+2 = 117 and largest number is 40.

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles. scalene, equilateral, acute, obtuse and right angled triangle.
A right angled triangle is a triangle in which one of the angles is 90 degrees. Trigonometric ratios show the relationship between the angles of a right angle triangle and its sides.
Let h represent the height of the house above water, hence using trigonometric ratios:
tan(26) = h / 531
h = 531 * tan(26)
h = 259 ft.

Answer: (3.5,-2)
Step-by-step explanation:
To solve this problem, all we have to do is plug in y=-2 into either equations from step one to find the coordinate. To make sure we have the right x-coordinate, let's plug in y for both equations.
4x-7y=28 [plug in y=-2]
4x-7(-2)=28 [multiply]
4x+14=28 [subtract both sides by 14]
4x=14 [divide both sides by 4]
x=3.5
------------------------------------------------------------------------------------------------------------
6x-5y=31 [plug in y=-2]
6x-5(-2)=31 [multiply]
6x+10=31 [subtract both sides by 10]
6x=21 [divide both sides by 6]
x=3.5
Now, we know the solution to the system is (3.5,-2).
Answer:
(3.5, -2)
Step-by-step explanation:
Hi there!
We are given a system of equations, and the value for y is already solved (y=-2)
We want to find the value of x
To do that, substitute -2 as y into either one of the equations in the system (the system has the equations 4x-7y=28 and 6x-5y=31) and solve for x
Let's use 4x-7y=28, although picking 6x-5y=31 is completely fine
Substitute -2 as y into the equation
4x-7(-2)=28
Multiply
4x+14=28
Subtract 14 from both sides
4x=14
Divide both sides by 4 and simplify
x=7/2, or 3.5
We found the value of x in the system
Substitute the values of x and y into a point form (x, y)
The solution is (3.5, -2)
Hope this helps!

The first tick mark is two eighths and has one data point. The second tick mark is three eighths and has three data points. The third tick mark is four eighths and has two data points. The fourth tick mark is five eighths and has no data points. The fifth tick mark is six eighths and has two data points. The sixth tick mark is seven eighths and has no data points. The seventh tick mark is one and has no data points. The eighth tick mark is one and one eighth and has no data points. The ninth tick mark is one and two eighths and has one data point. The tenth tick mark is one and three eighths and has two data points. The eleventh tick mark is one and four eighths and has no data points. The twelfth tick mark is one and five eighths and has no data points. The thirteenth tick mark is one and six eighths and has two data points. The fourteenth tick mark is one and seven eighths and has one data point.
1 inch
one and one eighth inches
one and two eighths inches
one and three eighths inches
Answer:The answer is 1 3/8 (D)
Step-by-step explanation:
If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.
Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.
