Answer: x = 10
Step-by-step explanation:
The sum of all interior angles in a polygon add up to 360°
Meaning to find X we grab those numbers/variables and make them equal to 360°. This will give us an equation.
106 + 94 + 135 + x + ( x + 5 ) = 360
335 + x + x + 5 = 360
340 + 2x = 360
subtract 340 from both sides
2x = 20
Divide by 2
x = 10
Now solve the angle equations to find their angle.
( 10 + 5 ) = 15
x = 10
Now to check if it's right add them together
106 + 94 + 15 + 10 + 135 = 360 ( ITS CORRECT )
Answer:
4
Step-by-step explanation:
Equation:
1/2x + 10 = 12
Subtract 10 from both sides:
1/2x = 2
Divide by 1/2 from both sides:
x = 4

Answer:
2 (x - 10) (x + 10)
Step-by-step explanation:
Factor the following:
2 x^2 - 200
Factor 2 out of 2 x^2 - 200:
2 (x^2 - 100)
x^2 - 100 = x^2 - 10^2:
2 (x^2 - 10^2)
Factor the difference of two squares. x^2 - 10^2 = (x - 10) (x + 10):
Answer: 2 (x - 10) (x + 10)
