44. You are in Home Depot to buy a new pool.

45. You want the length to be 4 feet longer than the width. You also plan on creating a 3 foot wide walkway on each side.

46. If you have exactly 520 square feet of wood for the deck, how big should the pool be?

48. You want the length to be 4 feet longer than the width. You also plan on creating a 3 foot wide walkway on each side. If you have exactly 520 square feet of wood for the deck, how big should the pool be?

49. You want the length to be 4 feet longer than the width. You also plan on creating a 3 foot wide walkway on each side. If you have exactly 520 square feet of wood for the deck, how big should the pool be?

50.  Area of pool and deck – Area of pool = area of deck

51. (x+10)(x+6)-x(x+4)=520 ft 2

52.  Area of pool + deck – Area of pool = area of deck (x+10)(x+6)-x(x+4)=520 ft 2 (x+10)(x+6)-x 2 -4x =520 ft 2 x 2 +16x+60-x 2 -4x =520 ft 2 12x+60=520 12x=460 x=38

53.  Area of pool + deck – Area of pool = area of deck (x+4+6)(x+6)-x(x+4)=520 ft 2 (x+10)(x+6)-x 2 -4x =520 ft 2 x 2 +16x+60-x 2 -4x =520 ft 2 12x+60=520 12x=460 x=38 W=38 ft, L=42 ft

54. Home Depot does not have a 38x42 foot pool available. Which of the following available pools is the most logical option? HDYK???
