Answer:

D) 32

Step-by-step explanation:

The volume of a cube is:

v=s³

512=s³

Take the cube root of both sides

s=8

To find the perimeter of a square,

p=4s

p=4(8)

p=32

So, D is your answer! Hope this helped!

Which represents the solution set to the inequality
Art [367]
5.1(3 + 2.2x) \ \textgreater \  -14.25 - 6(1.7x + 4)
Lets expand both multiplications first.
15.3 + 11.22x \ \textgreater \  -14.25 - 10.2x - 24
Simplify down the right side.
15.3 + 11.22x \ \textgreater \  -38.25 - 10.2x
Add 38.25 to both sides.
53.55 + 11.22x \ \textgreater \  -10.2x
Subtract 11.22x from both sides.
53.55 \ \textgreater \  -21.42x
Divide by -21.42 on both sides. Because we're dividing by a negative, we need to change the inequality direction.
-2.5 \ \textless \  x
This means, out of the options available, (-2.5, ∞) is the correct answer.
