Question

One-third of Kael’s backyard perimeter is represented by the expression 4x+18. What is the simplified expression to represent the whole perimeter?

Answer 1

If one-third of the backyard perimeter is represented by the expression 4x + 18, then the whole perimeter can be represented by multiplying this expression by 3:

3 * (4x + 18) = 12x + 54.

Therefore, the simplified expression to represent the whole perimeter is 12x + 54.
