Find the measure of the dilated image of segment CD, 6 units long, with a scale factor of 3. A. one-third units B. 2 units C. one-ninth units D. 18 units
D, because if you apply a dilation of three to a line with a length of 6, you'd multiply the two, getting an answer of 18. You know to multiply since the scale factor is a number larger than 1
