WORD PROBLEMS - QUADRATIC EQUATIONS 6. Noj is 5 years older than Jacob. The product of their ages is 84. How old is Noj? (3) 12 (4) 14 (2) 7 The length of a rectangle is three times its width. If the width is decreased by 1 inch and the length is increased by 3 inches, the arca of the new rectangle will be 72 square inches. Find the dimensions, in inches, of the original rectangle. 7. 8. A square and a rectangle have the same area. The length of the rectangle is three inches more than the side of the square. The width of the rectangle is two inches less than the side of the square. Algebraically, find the side of the square. The sum of the squares of two positive consecutive odd integers is 130. Algebraically, find the integers. 9. 10. Barb pulled the plug in her bathtub and it started to drain. The amount of water in the bathtub as it drains is represented by the equation L-5,2-N + 120, where 1 represents the number of liters of water in the bathtub and f represents the amount of time, in minutes, since the plug was pulled. 11. How many liters of water were in the bathtub when Barb pulled the plug? Show your reasoning 12. Determine, to the nearest tenth of a minute, the amount of time it takes for all the water in the bathtub to drain.
