Answer:
7a + 2a = 9a
Explanation:
the distributive property states that when a term is outside the bracket is will be multiplied by the terms inside it
A

first we have to distribute
A times 7 is 7a
2 times a is 2a
and considering that both 7a and 2a are like terms they can be added
therefor, 7a+2a=9a
