Add. (9h + 9) + (4h + 4) ____

Combine Like Terms: We have the expression (9h + 9) + (4h + 4). First, we need to combine like terms. Like terms are terms that contain the same variable raised to the same power. (9h + 9) + (4h + 4) = 9h + 4h + 9 + 4Add Coefficients and Constants: Add the coefficients of the h terms together and the constant terms together. 9h + 4h gives us 13h, and 9 + 4 gives us 13. So, 9h + 4h + 9 + 4 simplifies to 13h + 13.Check for Errors: Check for any mathematical errors in the previous steps. We added the coefficients of h (9 and 4) correctly to get 13h. We added the constants (9 and 4) correctly to get 13. There are no mathematical errors in the previous steps.

(9h + 9) + (4h + 4)

Combine Like Terms: We have the expression $(9h + 9) + (4h + 4)$ . $\newline$ First, we need to combine like terms. Like terms are terms that contain the same variable raised to the same power. $\newline$ $(9h + 9) + (4h + 4)$ $\newline$ = $9h + 4h + 9 + 4$
Add Coefficients and Constants: Add the coefficients of the $h$ terms together and the constant terms together. $\newline$ $9h + 4h$ gives us $13h$ , and $9 + 4$ gives us $13$ . $\newline$ So, $9h + 4h + 9 + 4$ simplifies to $13h + 13$ .
Check for Errors: Check for any mathematical errors in the previous steps. $\newline$ We added the coefficients of $h$ ( $9$ and $4$ ) correctly to get $13h$ . $\newline$ We added the constants ( $9$ and $4$ ) correctly to get $13$ . $\newline$ There are no mathematical errors in the previous steps.
