Rectangle QUAD has coordinates​ Q(0,0), ​U(0,​3), ​A(7​,​3), and ​D(​7,0). ​Q'U'A'D' is the image of QUAD after a dilation with center​ (0,0) and scale factor 6. What are the coordinates of point U ​'?

To find the coordinates of U' after a dilation with scale factor 6 and center at (0,0), we can multiply the coordinates of U(0,3) by the scale factor.

U'(x, y) = (0*6, 3*6) = (0, 18)

Therefore, the coordinates of point U' are U'(0, 18).
