Answer:
20 times
Step-by-step explanation:
The equation is...
9.5x+105=14.75x
105=5.25x
20=x
Let the width be x.
width = x
length = x + 8
The area is 20 ft²
x(x + 8) = 20
x² + 8x = 20
x² + 8x - 20 = 0
(x + 10) (x - 2) = 0
x = -10 (rejected) or x = 2
Width = x = 2 ft
Length = x + 8 = 2 + 8 = 10 ft
Answer: The width is 2 ft and the length is 10ft.
