Answer:
A and C.
Step-by-step explanation:
We add the real part and the imaginary part separately.
Adding A and C will give us 10 - 3i:
-3 - 4i + 13 + i
= -3 + 13 - 4i + i
= 10 - 3i.
This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent
so we solve like this

subtract -3 on each side one is canceled since its equal to zero
and other is -3-5= -8

now subtract -3 on each side
-3x-x is -4 so,
-4x=8
divide its equal to 2
X=2
Hope it helps! have an awesome day you should probably study the properties of parallelogram
