Dec 7, 2015

$1 - 12 i$

#### Explanation:

Combine like terms. In this scenario, you can add integers with integers, and imaginary numbers with imaginary numbers.

$\left(\textcolor{b l u e}{3} \textcolor{g r e e n}{- 5 i}\right) + \left(\textcolor{b l u e}{- 2} \textcolor{g r e e n}{- 7 i}\right)$

$\left(\textcolor{b l u e}{3 + - 2}\right) + \left(\textcolor{g r e e n}{- 5 i + - 7 i}\right)$

$\textcolor{b l u e}{1} \textcolor{g r e e n}{- 12 i}$
