Answer:
A
Step-by-step explanation:
Let width =w in
Length = 3w - 2 in
Perimeter of rectangle = 36 inches
2* (length + width ) = 36
2*(3w -2 + w) = 36
2* (4w -2 ) = 36
2*4w - 2*2 = 36
8w - 4 = 36
Add 4 to both sides
8w - 4 + 4 = 36 +4
8w = 40
Divide both sides by 8
8w/8 = 40/8
w = 5
Width = 5 in

6x-1 = 4x + 6 [ all sides of square are equal]
6x-4x = 6+1
2x = 7
x = 3.5 cm
Step-by-step explanation:
volume = [(15×11)+(½×15×8)] x 12
= (165+60) x 12
= 225×12
= 2,700 cm³
