I need help :( this problem is very confusing

Emily ,  don't put your whole name in the questions :, it's at the top of the page, anyway,     Eloper   .. :DDD

Step-by-step explanation:

It's arithmetic  b/c  you're just adding  1

arithmetic

1

1

are the answers ,  the last one is b/c that's the common difference.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
