Question

can't wait till I come to that city to be the one to be all around the world and there isn't a thing out there I haven't done for you so keep at it and don't let it get you down when I'm at that party drinking all  the liquor with your girls

Answer 1

Hello, thank you for taking the time to post your question!

When you have a term like this that is outside the parentheses you want to distribute it to both terms on the inside. On this one that becomes

3a(a + 4)

=3a^2 + 12a

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

Distribute 3a over both terms within the parenthesis.

 

Multiply 3a by a to get 3a²

 

Multiply 3a by +4 to get 12a

 

Add all terms by adding 3a² to 12a to get an answer of "3a² +12a"
