Answer:
12=12
Step-by-step explanation:
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.
2:3
?:36
36/3=13
2x13=26
26:36
26+3=29
29:36
Number 2 is 4x^5/3y^5 and 14 is 3125x^10
