PLS HELP! DUE TODAY! I WILL GIVE BRAINLIEST! In the following activity, match each pair of equivalent expressions.
3(x + 5)
9x - 2(3x - 3)
(x + 14) - (8 - 2x)
(7 - 2x) + (3x - 11)
(7 + 5x) + (-4x - 1)
-2x + 9 + 5x + 6
-4(x + 1) + 5x
-7 + 6x - 4x + 3
2(x - 2)
-3x + 6 + 4x

Matches are:

1 and 6

2 and 3

4 and 7

5 and 10

8 and 9

Step-by-step explanation:

First just expand all:

1. 3x + 15

2. 3x + 6

3. 3x +6

4. x - 4

5. x + 6

6. 3x +15

7. x - 4

8. 2x - 4

9. 2x - 4

10. x + 6

Please give brainliest! Thanks, hope this helps!

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
