There's a saying to this kind of equation: Rate + Time = Distance and B best fits the saying, so B must be right (Don't quote me on that, it may be wrong)
(-1,5)(5,5)
midpoint formula : (x1 + x2)/2, (y1+ y2)/2
(-1 + 5)/2 , (5 + 5)/2) =
(4/2 , 10/2) =
(2,5) <===
Answer:
A. The value of x is 5
B. The length of each side is 20!
Step-by-step explanation:
For part A., We can determine x by setting these equations to equal each other (as we know that all sides of a square are equal)! See below for how to:

For part B. sub x for 5 to get the side length of one side...

We already know that all sides are equal, so the side length of each side is 20!

Answer:
Yes!
Step-by-step explanation:
In Pythagorean Triples, the two legs always have to add up to be a greater number than the hypotenuse. In this case, 12 and 16 are the legs and 20 is the hypotenuse. The sum of 12 and 16 is 28. That is more than 20, so 12, 16 and 20 make a right triangle. I hope this helps you!
