Question

Are these expressions equivalent? Explain why or why not. 42 + 35 706 + 5)​

Answer 1

Yes, they are equivalent.

Explanation:

Both of the expressions equal to 77. 42+35 is easy, just add to get 77. To solve 7(6+5) remember PEMDAS which tells you to do parentheses first. So add 6+5, which is 11, then multiply by 7. 11*7 is 77, therefore the expressions are equivalent.
