Hey can you please help me posted picture of question
GREYUIT [131]
To solve this problem you must apply the proccedure shown below:

 1. You have the following expression:

 (3+3i)-(13+15i)

 2. If you want to substract both terms, you  need to substract the real numbers and the complex numbers. Then, you obtain:

 3+3i-13-15i
 (3-13)+(3i-15i)

 3. Then, you obtain the following result:

 -10-12i

 4. Therefore, as you can see, the correct answer is the last option (option D), which is:
 D. -10-12i
