The path of the train is modeled by the equation x2+y2+4x−6y−131=0. Given that all dimensions are in feet, what is the distance of the toy train from the center of the track at any point in time?

Solve for x and y a x= 13.3 y= 16.7 b x= 23.3 y= 12.5 c x= 7.5 y= 16.7 d x=7.5 y= 12.5

Aquadrilateral has exactly one pair of parallel sides. which name best describes the figure?
