Answer:volume is lengthxwidthxheight
Step-by-step explanation:
Length=3
Width=7
Height=10
3x7x10=210 inches ^3
First, distribute the 2 across the parenthesis.
10-3v+9v=28
Combine like terms on the left.
10+6v=28
Start to get the numbers on the right and the v alone on the left by moving the 10 to the right.
6v=28-10
6v=18
Divide to get the v alone.
v=3
Hope that helps.
