Pt3 please help this is the last part :/

the answer is d

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.

well what did you do it matters what you did : )

step-by-step explanation:

x = 3 ± √(5+y)
