On a coordinate plane, 2 quadrilaterals are shown. Quadrilateral Q R S T has points (negative 1, 0), (5, 0), (3.5, negative 6) a
nd (negative 2.5, negative 6). Quadrilateral Q prime R prime S prime T prime has points (negative 1, 2), (1, 2), (0.5, 0), and (negative 1.5, 0). Quadrilateral QRST is dilated and translated to form similar figure Q'R'S'T'. What is the scale factor for the dilation?
X+8/4-x+5/4 The first term in the series is a positive "x", and the third one is a "-x". Since these are opposites, they cancel out x+8/4-x+5/4 8/4+5/4 13/4 4 1/4
