Solve the polynomial inequality and graph the solution set on a number line. Express the solution set in interval notion. (X-7)(x+4)>0

Y=4x^2+x-1 solve using quadratic formula

Which choice represents the sample space ,s for this event

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.
