Use: L x W x H to find the volume.
(Length multiplied by the width which is then multiplied by the height of the prism.)
You haven't supplied the "output value."
Supposing that the "output value" were 15, then F(x) = x + 7 = 15, and x = 8.
1. bc/3 + a/xy + 3/ab
= b^2cxya + 3a^2b + 9xy/3xyab
2. (5/3y) + 2y - 12
=11/3y - 2
3. ?
Hope this helps and right! :)) Good luck
