Answer 1

Please help

Answer 2

The first one is true.

Answer 3

Thank you!!!!

Answer 4

that is because distributive property exists only in multiplication. For exam 3(2x+6) would be an example. The solution would be 6x+18. So this rules out the second and fourth options.

Answer 5

Also, associative property of addition is just saying that you can write it in different ways, because changing of parenthesis doesn't actually change the result. Which rules out the third option. So you are left with the first one. Look at the first and third option for the difference. You'll understand why. I hope I helped.

Answer 6

Yes, you did. Thank you!!!
