Distance formula:
(1-(-3))^2 - (-2-4)^2 = 16 + 36 = 20
B(You survey every 10th student entering school to find out the amount of time it takes them to get to school) is a good survey
N²+20n+100 = (n+10)(n+10)
Yes is it a perfect square trinomial
The formula for the area of a circle is π r^2.
3.14 (12x12) = 452.16
Approximately 450sqft
This function is in the form y=mx + b where m is your slope, so the slope is -2
