Question

the height of a box is 7 the length is three inches more than the width find the volume is 126

Answer 1

Answer:

answer c: 10

Step-by-step explanation:

v=H*W*L

280=7*W*(6+W)

280=42W+7W^2

40=6w+w^2

W^2+6W-40=0

(W-4)(W+10)=0

W=4

We can only use positive results

L=6+W

L=4+6=10

=10
