Question

Which expressions are equivalent to g+h+ (j+k)? Check all that apply.

Answer 1

It might be the third one

Answer 2

According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.

So answers 1. and 3. are correct.

Thanks Associative Property!
