Which is the simplified form of the expression

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

Asystem of equations has 1 solution. if 4x-y=5 is one of the equations , which could be the other equation ?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
