Question 414257: The length of a rectangular swimming pool is 2x -1 meters, and the width is x +2 meters. Write a polynomial A (x) that represents the area. Find A (5). Answer by mananth(16949) (Show Source):
You can put this solution on YOUR website! pool is 2x -1 meters, and the width is x +2 meters.
Area = L*W
Area = (2x-1)(x+2)
Area =2x^2+4x-x-2
A(x) =2x^2+3x-2
...
A(5)= 2(5^2)+3(5)-2
A(5)=50+15-2
A(5)=63 m^2
