The oldest child in a family of four children is twice as old as the yougest. the two middle children are 13 and 15 years old. if the average age of the children is 13, how old is the youngest child?

The youngest child is 8 years old.

8 x 2 = 16

8 + 13 +15 +16 = 52

52 / 4 = 13

it is c, trust i got your back lol

step-by-step explanation:

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.
