Suppose triangle ABC will be dilated using the rule D Subscript Q, two-thirds. Point Q is the center of dilation. Triangle A B C is 6 units away from point Q. The length of A B is 3, the length of B C is 7, and the length of A C is 8. What will be the distance from the center of dilation, Q, to the image of vertex A?
