Quadrilateral abcd has vertices a(0,0), b(2,0), c(3,4), and d(0,4). find the vertices of quadrilateral a'b'c'd' after a translation of 4 units right and 2 units down.

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.
