Answer:

21a + 17b

Step-by-step explanation:

To simplify, we need to distribute the 9 to the terms inside of the parentheses that it is being multiplied by and 4 to the terms inside of the parentheses that it is being multiplied by like so:

9(a)+9(b)+4(3a)+4(2b)

9a+9b+12a+8b

Add like terms

21a + 17b
