Matching Equivalent Expressions

Match each expression written in standard form to the equivalent expression in factored form.

15x?y2 + 3x

3xy(5x6y + 2)

15x7y2 + 4x3

x3(15x4y2 + 4)

15x7y2 + 6xy

3x(5x®y2 + 1)

15x7 + 104²

5(3x + 2y2)

How do I know which matches with which

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.
