Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
Answer:
142°
Step-by-step explanation:

10/12 = 2*5 / 2*6 = 5/6
15/18 = 3*5 /3*6 = 5/6
25/30 = 5*5 /5*6 = 5/6
But what's the 13/14 :(. You can't simplify it to 5/6 or something else.
Answer:
only D
Step-by-step explanation:
I think it is 156 but I don't know for sure.
I hope this helps!
