The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

Step-by-step explanation:

The perimeter is 150 ft, the length of the fence.

We add the lengths of the sides and set equal to the perimeter. Then we solve for x. Once we know x, we find the length of each side.

x + 2x + 0.5x + 45 = 150

3.5x = 105

x = 105/3.5

x = 30

Lengths of sides:

x = 30

2x = 2(30) = 60

0.5x = 0.5(30) = 15

45

The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
