Answer:
5i
Step-by-step explanation:
Using the rule of radicals
×
⇔ 
and
= i
Given

= 
=

× 
= 5 ×
× i
= 5i
The trick is to write appropriate equations and then solve the system of equations you've created.
"sum of two numbers is -5:" x + y = -5
"difference is -1:" x-y = -1
Add these two equations together. This will cause y to drop out, and you will be left with an equation in x alone:
2x = - 6, so x = -3. Subst. -3 for x in either equation, above, and find the corresponding y value.
Then write your solution as (-3, y ) (write in your value for y).
Your answer is D.
