The length of the other leg is 12, I think, but I'm not sure. Sorry if it's wrong.
Answer:
x^2 - 8x = -5
x^2 -8x +16 =-5 +16
( x-4)^2 = 11
x^2 - 8x+5 = (x-4)^2 -11
Step-by-step explanation:
Soccer : (12.3 + 13.2 + 12.5 + 11.3 + 14.4) / 5 = 63.7 / 5 = 12.74
track : (12.3 + 11.2 + 11.7 + 12.2 + 13.7) / 5 = 61.1 / 5 = 12.22
difference is : 12.74 - 12.22 = 0.52 <=
Answer:
