Add. (q + 9) + (6q + 9) ____

Remove Parentheses: We have the expression (q + 9) + (6q + 9). The first step is to remove the parentheses since they are not necessary when adding terms. (q + 9) + (6q + 9) becomes q + 9 + 6q + 9.Combine Like Terms: Now, we combine like terms. The like terms are the terms with the variable q and the constant terms. q + 6q gives us 7q, and 9 + 9 gives us 18. So, q + 9 + 6q + 9 simplifies to 7q + 18.Final Simplification: There are no further simplifications to be made, so the final expression is 7q + 18.

(q + 9) + (6q + 9)

Remove Parentheses: We have the expression $(q + 9) + (6q + 9)$ . The first step is to remove the parentheses since they are not necessary when adding terms. $(q + 9) + (6q + 9)$ becomes $q + 9 + 6q + 9$ .
Combine Like Terms: Now, we combine like terms. The like terms are the terms with the variable $q$ and the constant terms. $\newline$ $q + 6q$ gives us $7q$ , and $9 + 9$ gives us $18$ . $\newline$ So, $q + 9 + 6q + 9$ simplifies to $7q + 18$ .
Final Simplification: There are no further simplifications to be made, so the final expression is $7q + 18$ .
