C + 2c + 12 = 75
Combine like terms:
3c + 12 = 75
Subtract 12 to both sides:
3c = 63
Divide 3 to both sides:
c = 21
The complex conjugate of <span>7i</span><span> is </span><span>−7i </span>The complex conjugate of a number
z is a number with opposite imaginary part.
So if <span>z=a+bi</span> then conjugate is: <span><span>¯z</span>=a−bi</span> for any <span>a,b∈R</span>
We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate <span>¯z</span> are symetrical according to "real part" axis.

Answer:
19.26$
Step-by-step explanation:
Sold DVD for
