2(3x) and 2(-9)
so 2*3x equals 6x and 2*-9 equals -18
6x-18
A cube has 6 sides.
A cube is all made up of squares.
So, we need to find the area of one cube and multiply that by 6.
Length * width= area
40*40= 1,600
Multiply that by 6.
1,600*6= 9600
Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.
9,600 (the unit) ^2
I hope this helps!

X = 2a - b²
x - 2a = b²
√x-2a = b
Just to clarify, all of x-2a is under the square root.
