Answer:
length = 36 ft; width = 12 ft
Step-by-step explanation:
Let the width be x.
The length is 3x.
The perimeter is the sum of two lengths and two widths, and it equals 96 ft.
3x + 3x + x + x = 96
8x = 96
x = 12
Width = x = 12 ft
Length = 3x = 3(12 ft) = 36 ft
Step-by-step explanation:
given
( x³ -64)/ x - 4
= (x³ - 4³) / x - 4
= (x - 4) ( x² + 4x + 16 ) / (x - 4)
( x- 4 ) will be cancelled out then
= x² + 4x + 16
Answer:
x<-32

I hope this helped have a good night
50 - 5n = 15
if you need to find the number n then
50 - 5n = 15
-5n = -35
n = 7
