A box shaped like a rectangular prism has a height of 17 in and a volume of 2.720 in^3. The length is 4 inches greater than twice the width. What is the width of the box? O -10 in
O 8 in
O 20 in
O 40 in

Width = W in.
Length = (2W + 4) in.

V = L * W * h = 2720 n^3.
(2W+4) * W * 17 = 2720
2W^2+4W)*17 = 2720
34W^2 + 68W - 2720 = 0
W^2 + 2W - 80 = 0
-80 =-8*10.
(W-8)(W+10) = 0

W-8 = 0
W= 8

W+10 = 0
W = -10

Use positive value of W: W = 8.
