Acylinder has a volume of 216π cubic feet and a height of 18 feet. what is the area of the base?

12 π ft    

Step-by-step explanation:

im pretty sure its x = -6

Step-by-step explanation:

Reorder the terms:

-12 + 3x = 5x

Solving

-12 + 3x = 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-12 + 3x + -5x = 5x + -5x

Combine like terms: 3x + -5x = -2x

-12 + -2x = 5x + -5x

Combine like terms: 5x + -5x = 0

-12 + -2x = 0

Add '12' to each side of the equation.

-12 + 12 + -2x = 0 + 12

Combine like terms: -12 + 12 = 0

0 + -2x = 0 + 12

-2x = 0 + 12

Combine like terms: 0 + 12 = 12

-2x = 12

Divide each side by '-2'.

x = -6

Simplifying

x = -6
