The area of a rectangular swimming pool is 10x2 – 19x – 15. The length of the pool is 5x + 3. What is the width of the pool? (1 point) Responses 2x – 18 2 x – 18 2x – 5 2 x – 5 5x – 5 5 x – 5 5x – 22
To find the width of the pool, you need to divide the area by the length.
Area = 10x^2 – 19x – 15
Length = 5x + 3
Width = Area / Length
Width = (10x^2 – 19x – 15) / (5x + 3)
Width = (5x + 3)(2x - 5) / (5x + 3)
Width = 2x - 5
Therefore, the width of the pool is 2x - 5.
