If A= ("-2" 6 1) (1 9 "-6)" ("-9" 9 "-9)" and B= ("-5" 9 6) (-2 "-7" 4) (1 10 "-1)," find "-4A" + 6B

idk

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.
