a) b^3
b) x^3
Step-by-step explanation:

<h3>a)</h3>

__
<h3>b)</h3>

Answer: A
Step-by-step explanation:
This is because...
1st. Simplify both sides of the equation (distribute the 4 and combine like terms)
6 + -x = 20 + 4x + -4 (distributed 4)
-x + 6 = 4x + 16 (combined like terms)
2nd. Subtract 4x from both sides.
3rd. Subtract 6 from both sides.
4th. Divide both sides by -5.
Area: 3.14*10*10
=314
Perimeter: 3.14*20
=62.8
