Just put the numbers under one square root symbol and try to simplify.
Answer:
B = 0
Step-by-step explanation:
do the y2-y1 over x2-x1 to check
so 5-0 = 5
-2-3 = -5
-5/5 = -1 slope
points (-2, 5) and (3, 0)
Answer:
720
Step-by-step explanation:
The permutation looks like this for that set of data:

and the formula to solve it like this:

which simplifies down to

Since every number less than 8 in the numerator cancels out with the denominator, we have

which equals 720
