Moira buys a new rectangular rug that is 3 inches shorter than her old rectangular rug. The area of the new rug is (x^2 + 2x - 15)in^2. The rug is 0, 5, 7 or 15 inches Wider or Narrower?
The area of the new rug is x² + 2x - 15 Since A = l x w The new rug is 3 in shorter than her old rug, so we divide the area by (x - 3) (x² + 2x - 15) / (x - 3) By factoring (x - 3)(x + 5) / (x - 3) Cancelling out terms x + 5 The width is 5 inches wider
