2. A scout troop travels in 5 cars. Each
car holds 4 people. One person in
each car is a parent. How many of the
people are NOT parents?

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
