Multiply both numerator and denominator of
by the complex conjugate of the denominator, -2+9i.

Multiplication can be transformed into difference of squares using the rule:
.

By definition, i² is -1. Calculate the denominator.

Multiply complex numbers 5-3i and -2+9i in the same way as you multiply binomials.

Do the multiplications in
.

Combine the real and imaginary parts in -10+45i+6i+27.

Do the additions in
.

Divide 17+51i by 85 to get
.

The real part of
is
.

Answer:
m>a is 40
Step-by-step explanation:
4x + 50 = 90
4x = 40
x = 10
10*4 = 40
M>A = 40
Answer:
slope: -3/4 y-intercept: 3 equation: y=(-3/4)x+3
Answer:
9 and 41 over 51
Step-by-step explanation:
divide 41 2/3 by 4 1/4
Answer: The answer should be 38.
I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.
Step-by-step explanation:
2.3 (14+6) -2 to the power of three
2.3 (20) -2 to the power of three
2.3 (20) -8
46-8
38
I really hoped this helped and if I got it wrong with the t just reply to me c:
