30 x 30 = 900
This is the surface area of one side
900 x 6
Multiply by 6 to get the surface area of all 6 sides of the cube
900 x 6 = 5400
The slope is 1/5
I hope this helps!!!!
3(2x-6)-7x+4
3*2x=6x. 3*-6=-18
-7x+6x=-1x. -18+4=-14
-1x/-1=x. -14/-1=14
X=14
6x + 1 = 2x + 10 + 79
6x + 1 = 2x + 89
4x = 88
x = 22
