The area of a rectangular swimming pool is 10x^2 - 19x - 15. The length of the pool is 5x + 3. What is the width of the pool?
a. 2x - 18
b. 2x - 5
c. 5x - 5
d. 5x - 22
To find the width of the pool, we need to divide the area of the pool by the length.
Width = (Area) / (Length)
Width = (10x^2 - 19x - 15) / (5x + 3)
Using long division or synthetic division, we get:
Width = 2x - 5
Therefore, the width of the pool is 2x - 5.
So, the correct answer is:
b. 2x - 5
