Answer:

The answer is A) -1 + 12i

Step-by-step explanation:

(7 + 3i) + (-8 + 9i)

(7 - 8) + (3 + 9)i

7 - 8 = - 1

3 + 9 = 12

- 1 + 12

5 Select the correct expressions. Which expressions are equivalent to 3x + 2(x - 1) - 4? 3x + 2x - 2 - 4 5x - 6 3(x-4) 3(x + 2)
beks73 [17]

Your question is a bit unclear, but I will try to answer it anyway.

The expression 3x + 2(x - 1) - 4 simplified is:

3x + 2(x - 1) - 4

= 3x + 2x - 2 - 4

= 5x - 6

I cannot tell what the answers are but I am guessing they are these?:

A) 3x + 2x - 2 - 4

B) 5x - 6

C) 3(x - 4)

D) 3(x + 2) - 6

E) 6(x - 1)

Answer A is one, and so is answer B. If I read your question accurately.

I hope I helped!
