The height of a box is 5 inches. It's length is 5 inches more than it's width. Find the length if the volume is 120.

8 Inches

Step-by-step explanation:

The length would be w+5, making your equation (5) (w+5) (w) = 120, which can be simplified to 5w²+25w-120=0. Then take out a GCF of 5, giving you 5 (w²+5w-24) = 0. Find the factors and get (w+8) (w-3). Your solutions are - 8 and 3. - 8 can be taken out, so the final answer is 3. Then you plug it back into the length, so 3+5 is 8.
