De has endpoints d 0 3

de has endpoints d(0,3) and e(0,12). find the length of de and round to nearest tenth.Answer: The length of side DE is 9 units. Step-by-step explanation: Given that the co-ordinates of the end-points of DE are D(0, 3) and E(0, 12). If DE is dilated by a scale factor of 2 and the center of dilation is 0 0 what are the coordinates of D and E. A line segment has endpoints C-3-6 and D-6-4.Top Elite Math Tutors.
