Step-by-step explanation:

(10x)/10 = 20/10

(10/10)x = 20/10

(1)x = 2

x = 2

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.
