Question

Last problem! Thank you! You don’t have to answer 7...

Answer 1

NO.

Explanation:

This is why:

2x + 2 = 4x - 11

-4x - 4x

_______________

-2x + 2 = -11

- 2 - 11

____________

-2x = -22

___ ___

-2 -2

x = 11

2[11] + 2 = 4[11] - 11

22 44

24 ≠ 33

So, use the Segment Addition Postulate:

[2x + 2] + [4x - 11] = 9x - 30

-9 + 6x = 9x - 30

- 9x - 9x

________________

-9 - 3x = -30

+9 + 9

____________

-3x = -21

x = 7

Solving for AB

`4(7) - 11 = 28 - 11 = 17`

Solving for BC

`2(7) + 2 = 14 + 2 = 16`

Solving for CA [MUST add up to thirty-three]

`9(7) - 30 = 63 - 30 = 33☑`

So guess what? THEY DO ADD UP TO 33.☑
