Answer:
the coordinates of point D' are (42,0).
Explanation:
To perform a dilation with center (0,0) and scale factor 7, we multiply the x and y coordinates of each point in QUAD by 7.
Q(0,0) -> Q'(07, 07) = Q'(0,0)
U(0,2) -> U'(07, 27) = U'(0,14)
A(6,2) -> A'(67, 27) = A'(42,14)
D(6,0) -> D'(67, 07) = D'(42,0)
Therefore, the coordinates of point D' are (42,0).
