your friend runs for (x² – 225) seconds at a rate of

per second. how far does your friend run?

(x + 15) / 2

Step-by-step explanation:

Distance = rate × time

d = (x² – 225) / (2x − 30)

d = (x – 15) (x + 15) / (2 (x – 15))

d = (x + 15) / 2

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
