Add (3 - 5i) + (-2 + 8i). Sum of real parts: Sum of imaginary parts: i
Dafna1 [17]

The correct answer is 1 + 3i.

In order to get the answer to this, only add like terms. Add first the constants in the front.

3 + -2 = 1

Now add the imaginary terms

-5i + 8i = 3i

Then you can put the two together as a term and write as 1 + 3i.

natulia [17]

Answer:

Step-by-step explanation:

9) 24=6(-x-3)

   24=-6x-18

   42=-6x

   x=-7

10) 75=3(-6n-5)

     75=-18n-15

     90=-18n

     n=-5

11) -3(1+6r)=14-r

   -3-18r=14-r

    17=-17r

    r=-1

12) 6(6v+6)-5=1+6v

    36v+36-5=1+6v

    36v+31=1+6v

    30=-30v

     v=-1

13) -4k+2(5k-6)=-3k-39

    -4k+10k-12=-3k-39

    6k-12=-3k-39

    9k=-27

     k=-3

14) -16+5n=-7(-6+8n)+3

     -16+5n=42-56n+3

     -16+5n=45-56n

     61=-61n

     n=-1
