Answer:

18x+36

Step-by-step explanation:

We are given the expression:

9(2x+6)-18

We want to simplify the expression. First, let's distribute the 9. Multiply each term inside the parentheses by 9.

(9*2x)+(9*6)-18

(18x)+(54)-18

Combine like terms. There are 2 constants (terms without variables): 54 and -18. We can add them together.

(18x)+(54+-18)

(18x)+(54-18)

18x+36

The expression 9(2x+6)-18 is equivalent to 18x+36
