It's urgent 'polygon abcd has sides with these lengths: , 5 units; , 4 units; , 4.5 units; and , 7 units. the slope of is 5, the slope of is 0.25, the slope of is -2, and the slope of is 0. the polygon is dilated from point a by a scale factor of 1.2 to form polygon a′b′c′d′. match the slopes and lengths of the sides of polygon a′b′c′d′ to their values.
