We'll look at two points on both pentagons.point e is located at (2,0). point e' is located at (4,0). to find the scale factor of the dilation, divide the x and y points of the new image by the original image: the y values are irrelevant to this problem, as both points are on the line x = 0. the scale factor for this dilation is 2.point u is located at (3,2). point u' is located at (6,4). divide the x and y values of the points to find the scale factor: the scale factor is 2.based on this information, we can conclude that house was expanded by a scale factor of 2 to create h'o'u's'e'.
