F(6) = 6 + 6 = 12
g(4) = 4 - 2 = 2
12 + 2 = 14
The answer is 14
If the length of a side is x, then the surface area of a face of the cube is x squared. there are six sides in a cube so 6(x^2) would be the surface area.
6(x^2)=150
(x^2)=25
x=5
To the right is postive so negive numbers with be on the left and 7 will be above 0 so locate 3 backwards from 0 and go up 7
