Write a function rule for the area, a, of a triangle whose base, b, is 2 cm less than seven times the height, h. what is the area of the triangle when the height is 14 cm?

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.
