Answer:
Yes, they are equivalent.
Step-by-step 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.
