So can someone help me but can yall pls explain it

Answer:
A
Step-by-step explanation:
a(7+2)
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
Answer:
7a + 2a = 9a
Step-by-step explanation:
the distributive property states that when a term is outside the bracket is will be multiplied by the terms inside it
