A. Re(z)= 32 and Im(z)= 41.9
The real part of a complex number z=a+bi is ‘a’, and the imaginary part is ‘b’
55+added=133
added=amount addeed per week times 6=6x
55+6x=133
minus 55 both sides
6x=78
divide both sides by 6
x=13
add 13 per week
y=13x+55
Answer:

Step-by-step explanation:

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

Zero commutative<span>property of multiplication. </span>The zero commutative property of multiplication states that when any number is multiplied by 0 the result is always zero
With some simple rearrangement, we can rewrite the numerator as

Then factorizing the difference of squares,
, we end up with
