Answer:
x ≥ −2
Step-by-step explanation:
This problem deals with inequalitites.
The expression is
x*2 ≥ −4
If we divide by 2 each side of the expression, we get
x* 2 / 2 ≥ −4 / 2
x ≥ −2
Which appears in your answer list

Answer:
The Pythagorean Theorem states that 
Step-by-step explanation:
This formula applies to the side lengths and means that the length of leg "a" squared, plus the length of leg "b" squared, will equal the length of hypotenuse "c" squared. Please state a more specific question so I can go into more detail if you need it :)
Here, both sides are equal, represented by - sign.
So, 4x + 12 = 60
4x = 60 - 12
x = 48/4
x = 12
In short, Your Answer would be 12
Hope this helps!
