Answer 1

First distribute 9 into the parenthesis, can you do that?

Answer 2

no how do you do it?

Answer 3

Just multiply 9 and 8 first... 72 right? And add "a" on the end changing it to 72a. Then multiply 9 and 5 changing it to 45.

So all we have left to do is:

72a + 45 + 6a

Can you combine like terms? Meaning adding 72a and 6a?
