The sum of number and 12 is 30. determine the number

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.

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)

If the scale factor between two circles is 2x/5y what is the ratio of their areas?
