Which expression gives the distance between the points (2, 3) and (4, -3)?
O A. (2-3)* +(4+3)
O B. (2-4)* +(3+3)
O C. (2-3)* + (4 +3)
O D. (2-4)2 + (3+3)?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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.
