Sorry I'm not sure if I'm right just my thinking...
set the number to be x so that (5x+2)(3x-4)??
Answer:
y=mx+b
Step-by-step explanation:
4 miles because there are 5280 ft in one mile so if you were to multiply that by 4 you would get 21120 ft
A(area) = b(base) * h(height)
A = 56 * 157
A = 8,792 mi^2
