Answer:

d. 6-19i

Step-by-step explanation:

(5-8i)+(1-11i)

Step 1: Combine like terms within the parenthesis. There are no like terms within the parenthesis. So, drop the parenthesis and move on to the next step.

(Remember!! If you would have had a negative sign in front of either parenthesis, you would need to distribute out the negative sign).

5 - 8i + 1 - 11i

Step 2: Now add like terms.

5 + 1 - 8i - 11i

6 - 19i

You can't combine any more like terms, so this is your final answer.

6 - 19i
