1/10 of an hour (D) is correct. Hope this helped :)
Given the expression (8+3i)+(-2+i)
We need to simplify it.
(8+3i)+(-2+i)
First we have to remove the parenthesis.
8+3i-2+i
As we know that multiplication of positive and negative is negative.
Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.
8-2 +3i+i
6+4i
We have got the required answer.
The simplified answer is 6+4i.

Answer:
Caras hourly wage is $10.08 after 3 years
Step-by-step explanation:
4% of 9
0.04 x 9 = 0.36
then you multiply 0.36 by 3 because you are solving for 3 years.
0.36 x 3 = 1.08
then you add 1.08 to 9 because Cara's wage goes up $1.08 in 3 years
1.08 + 9 = 10.08
answer:
Cara's hourly wage is $10.08 after 3 years of working
