Hi there,

I hope you and your family are staying safe and healthy!

Answer: 7i + 9

Step-by-step explanation:

(7 + 5i) - (3 - 4i) - (-5 + 2i)

We need to start by re-arrange the terms

(5i + 7) - (4i + 3) - (5 + 2i)

Then we need to distribute

5i + 7 + 4i - 3 - (-5 + 2i)

Once again, we need to re-arrange the terms

5i + 7 + 4i - 3 - (2i - 5)

Again, we need to redistribute

5i + 7 + 4i - 3 - 2i + 5

Now add

5i + 9 + 4i - 2i

= 7i + 9

If you find this answer helpful, please leave 5 stars and a like.

Happy to help!
