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 third number = 33
Step-by-step explanation:
First number = x
Second number = x + 7
Third number = 3x
x + x + 7 + 3x = 62 Combine like terms
5x + 7 = 62 Subtract 7 from both sides
5x = 62 - 7
5x = 55 Divide by 5
5x/5 = 55/5
x = 11
Step-by-step explanation:
you need to solve this equation:
(3x-5)+(10x-7)=180° because they are inner angles so their sum is 180°
