Acarpenter has several boards of equal length. he cuts 3/5 of each board. after cutting the boards he has enough pieces left over to make up the same length as 4 of the original boards. how many boards did the carpenter start with?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
