Answer:
So x=4 and y=-5 would work.
Step-by-step explanation:
When you multiply complex conjugates, you get a real result.
Example:
I replace with -1 since .
is a real number (there is no imaginary part, no i).
So what is the conjugate of 4+5i?
4-5i
So x=4 and y=-5 would work.
A multiple of the complex conjugate would work as well.
This is still a real number; there is no imaginary part,no i.
Answer:
The two integers are C, 4 and -3.
Step-by-step explanation:

Answer:
12) C. 13 ft by 13 ft
13) B. 9 ft by 9 ft
Step-by-step explanation:
12.
If the porch is a square, then a side length should be the same as the other side length. Therefore the side length must be the which simplified is 13.
