Answer:
18x+36
Step-by-step explanation:
We are given the expression:
[tex]9(2x+6)-18[/tex]
We want to simplify the expression. First, let's distribute the 9. Multiply each term inside the parentheses by 9.
[tex](9*2x)+(9*6)-18[/tex]
[tex](18x)+(54)-18[/tex]
Combine like terms. There are 2 constants (terms without variables): 54 and -18. We can add them together.
[tex](18x)+(54+-18)[/tex]
[tex](18x)+(54-18)[/tex]
[tex]18x+36[/tex]
The expression 9(2x+6)-18 is equivalent to 18x+36
