In step 2, Rhett used the associative property.

In step 3, Rhett used the commutative property.

In step 4, Rhett's answer is incorrect.

Answer 1

He did not use the distributive property, nor is the answer incorrect

Answer 2

I forget what the associative and commutative properties are though

Answer 3

thx

Answer 4

I believe the answer is B, as the associative property talks about how you can add or subtract numbers, regardless of their grouping. Notice how they choose to switch which ones they subtract from each other in part 2

Answer 5
