Question

Help? Picture is listed. Directions say "Determine whether the two expressions are equivalent. If so, tell what property is applied. If not, explain why."

Answer 1

Wish I could help but the picture is not pulling up sorry!

Answer 2

You just have to expand the expressions.
For the first one, 72-(63-8) = 17 (brackets first, so 72-(55) which is 17)
and (72-63)-8 = 1, so they are not equivalent. The reason why they aren't equivalent is because the brackets are around different parts of the equation, so you are solving it differently and getting a different result.
