Simplify the following complex expression
(3 + 4i)(2 – 2i)
a.-2+2i
b.
14 – 21
c.14+ 21
d. 6 - 6i

2/5

step-by-step explanation:

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

hope this !
