The figure above shows the lengths of thesides of a rectangle in cm. find the valuesof x and y and then the area of the rectangle.sides: top= 3x - yleft= 3y + 4bottom= 2x + yright= 2x - 3 use both methods, elimination and substitution, if possible.

The table respent two linear functions the equation respented by the first tables is given

The parabola opens: y=√x-4 (principal square root) up down right left
