Answer:

ACTUALLYYY the other person is wrong, the answer would be D/ 11 + 7i

Step-by-step explanation:

(1 + 2i) * (5 - 3i) = 1(5 - 3i) + 2i(5 - 3i)

                          = 5 - 3i + 10i - 6i^2

                          = 5 + 7i - 6(- 1)

                          = 5 + 7i + 6

                          = 11 + 7i

Best way I can show you sorry if it doesn't make sense but its O 11 + 7i !
