8 (2x - 14) + 13 = 4x -27
distribute 8 through the parentheses
16x - 112 + 13 = 4x - 27
combine like terms
16x - 99 = 4x -27
subtract 4x from each side
12x - 99 = -27
add 99 to each side
12x = 72
divide each side by 12
x = 6
Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
What I’m so confused but i hope you get the awnser from someone eklse not me
V = 2x^3 + 6x^2
x = 12
V = 2(12^3) + 6(12^2)
V = 2(1728) + 6(144)
V = 3456 + 864
V = 4320
