I need help on this question for middle school.

2y+12

Step-by-step explanation:

4(7/8y-4-3/8y+7)

first, in the parentheses (because of PEMDAS), combine like terms

4(7/8y-3/8y+-4+7)

4(4/8y+3)

Simplify 4/8y

4(1/2y+3)

now apply distributive property and multiply each number by 4

2y+12

Hope this helps!

(2y + 12)

Step-by-step explanation:

4(7/8y-4-3/8y+7)

Sorry my answer wasn't complete last time:) Hope this is better:)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
