Which of the following demonstrates the distributive property?

3(4a + 2) = 12a + 6

3(4a + 2) = 12a + 2

3(4a + 2) = 4a + 6

3(4a + 2) = 7a + 5 asap pls need

Distributive property basically means say you have 3(4a + 2) what you are going to do is multiply the 3 and 4 together to make 12a then you are going to multiply 3 and 2 to get 6 so then 3(4a + 2) is going to turn into 12a + 6. does that make sense??
