Question

Perform the indicated operation. (7 - 11i) + (-3 + 5i)
a. 34
b.4-16i
c.4-6i

Answer 1

c because you combine like terms 7+-3=-4 -11i+5i=-6i so your answer is c

Answer 2

c. 4-6i

Explanation:

The equation can be simplified using addition and subtracting:

The expression is (7-11i)+(-3+5i)

We can remove the the brackets and end up with 7-11i-3+5i

We can simplify by adding the i terms and normal number terms

`=i(-11+5)+7-3`

`=4-6i`

The answer is c
