Its D

Answer 2

i think this is called "multiply" not "simplify"

Answer 3

\[(1 + 2i) \times (5 − 3i) \] you can either multiply out as you see it, or use
\[(a+bi)(c+di)=(ac-bc)+(ad+bc)i\]

Answer 4

it is in fact D, although getting a letter for an answer from someone here is not going to help you much if you actually have to learn how to do it
