The answer would be A. I just did this yesterday. Do you want the steps?
Using the Pythagorean theorem:
x^2 + (x-2)^2 = (√20)^2
Simplify the right side:
x^2 + (x-2)^2 = 20
Subtract 20 from both sides:
x^2 + (x-2)^2 - 20 = 0
Factor:
(x-4)(x+2) = 0
Solve for each x:
x = 4 and x = -2
The side cant be a negative value, so the answer would be x = 4
The answer is B.
Left side: 63, 72, 16 right side: 36, 4, 35
you do 77 divided by 14 you get 5.5 so the greatest number of teams is 5.
