Ok so you have to use PEMDAS . so first you have to get rid of the parenthesis.
2 x 6x = 12x then 2 x -5= -10
12 + 5x -8 = 12x -10
combine now: 12 - 8 = 4
5x + 4 = 12x - 10
- 4 -4
5x = 12x -14
-12x=-12x
-7x = -14
-14/-7
x=2
Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D

Answer:
true
Step-by-step explanation:
Using the order of operations to evaluate the expressions, we have ...
8 + 5(8) ≥ 9(5)
8 +40 ≥ 45
48 ≥ 45 . . . . . true
