Answer:
C) 5 - 13i
Step-by-step explanation:
The parentheses don't matter because it is addition. (I think it is the addition associative postulate)
So, we have: <em>8 - 15i + -3 + 2i</em>.
Then, we combine like terms: 8 - 3 = <em>5</em>, -15i + 2i = <em>-13i</em>.
Putting those two values gives us 5 - 13i.
