The volume of a cube is length x width x depth. In a cube all would be equal therefore.
<span>x^3= 64 </span>
<span>x =4 </span>
<span>The area in square feet of one side would then be length x width </span>
<span>There are 6 sides so the surface area of the cube would be </span>
<span>(4)(4)(6) = 96 square feet</span>
It’s negative 4 because the scale shows there is 4 lines
With
, we have

Then the difference quotient is

since <em>h</em> ≠ 0.
You combine both 2x-12 and x+2 and 11 which makes the equation
2x-12+x+2= 11
The you get your answer which is
X=7
