So we want to know what x times 2 is. So think about this: multiply x with 2. We can find out what works and what doesn’t. So remind yourself that if you are multiplying a negative number, you get a negative. And when you minus a negative with a positive it’s the same as a negative + a negative. So it can’t be a negative as the answer is 0. Try each positive and you will find the answer to be
X=8
Answer:
14
Step-by-step explanation:
the absolute value of -8 is 8
the absolute value of 6 is 6.
6 + 8 = 14
give brainliest please!
hope this helps :)
The general formula for the distance between two points is

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

So, we're left with

but the square root of a square is the absolute value of the object being squared:

which is this case means 
which is the correct length of the side.
Answer:
The answer is the option D
