Answer:
Step-by-step explanation:
if they're equivalent, when you plug in either 10 or 6 for x, they should both equal the same.
x=10, 8(10)+40=120.... 8(10+5)=120. so they equal. also test 6
8(6)+40=88. 8(6+5)=88
they are equivalent since they both equal each other, no matter what you plug in. reason being that the 8(x+5) is the factorized version of 8x+40
