Which of the following is a radical equation? x StartRoot 3 EndRoot = 13 x + StartRoot 3 EndRoot = 13 StartRoot x EndRoot + 3 = 13 x + 3 = StartRoot 13 EndRoot The answer is the selected option.

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.

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1
