Answer: A(x) = 15 ft + 2x
EXPLANATION
Given,
The dimension of the rectangular garden is 20 ft by 15 ft.
Dimension of a rectangle is written as Length by Width
This implies that,
Length of the garden = 20 ft
Width of the garden = 15 ft
The garden has a walk around it of width x.
The combined width of the garden = Width of garden + 2x
[we are adding twice the width of the walk because it is
around the garden (this means it will add to the width of the garden on both the left and right sides)]
Combined width of the garden, A(x) = Width of garden + 2x
Since width of the garden = 15 ft
A(x) = 15 ft + 2x
Answer:
K = -2
It is -2 because when you plug in the coordinate y/k = -2
Answers:
area = 50.24 square yards
circumference = 25.12 yards
values are approximate
================================================
Work Shown:
d = 8 is the diameter
r = 4 is the radius, half the diameter
pi = 3.14 approximately
C = 2*pi*r = circumference
C = 2*3.14*4
C = 25.12 yards is the circumference. The circumference is the distance around the circle, aka the perimeter
An alternative formula you can use is C = pi*d
-------------------
A = area of circle
A = pi*r^2
A = 3.14*4^2
A = 50.24 square yards is the area
I believe the answer is 34.
Explanation:
I used the equation a^2 + b^2 = c^2
10 = a
24 = b
Plug it in.
10^2 + 24^2 = c^2
Get rid of the ^2
10 + 24 = 34
