Answer:
20.
Given, complex number is 10+5i .
We need to find sum of the given complex number and its conjugate. The conjugate of 10+5i is 10-5i. Therefore, the sum will be 10+5i+10−5i=20.
The answer is D
Because there are two x’s
And 5 number 1’s
So 2x=5
It is 7. None of the other ones fit at all
Answer:
A+B=B+A
