If the absolute value of x is 4, what is the value of x a: -16 or 16 b: -4 c: -4 or 4 d: 4

We know that when we take the absolute value of something, we are essentially taking the integer and making it a positive number regardless of the sign - basically to show magnitude more than anything.

Therefore, if it doesn't matter what the sign (positive or negative) is, then we can safely say that in this case, x is C) -4 or 4.
