Answer 1

You would multiply the like (or similar) terms together. 

2*4= 8

-5i*7i= -35i

The correct answer is "A".

I hope this helped you.

Answer 2

Your answer is a; since one set of numbers have an "i" next to them, you multiply those terms together. The normal terms multiply together, since they are "like terms," meaning that they don't have variables (or they have the same variable). therefore, you end up with 8-35i
