I think it might be expression one =14 i think and number 2 is obviously is 19 but you would put parenthesis around 5+4_2+6
I think i did this right its been a while since i did this
Can u explain it a little more clearly...
It would be C, as in cubic inches.
Whenever you are dealing with a 3D volume, always use the cubic route
0.5(20x - 50y + 36) - 0.25(-100x + 40y - 12)
10x - 25y + 18 + 25x - 10y + 3
35x - 35y + 21
