In this figure, GH has endpoints G(-2,4) and H(2,-3). What are the coordinates of G' and H' after GH is dilated by a factor of 3 with the center of dilation at the center of dilation at the origin? G’(_,_)
H’(_,_)

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
