The area of a rectangle is x2 - 2x - 15 and the length of the rectangle is x + 3. Find the width of the rectangle.
2 answers:
Answer:
<em>Width of the rectangle is </em><em>(x-5) </em>
Step-by-step explanation:
We know that, the product of length and width gives the area of the rectangle.
The area of a rectangle is given as,


Factoring the area,




Putting it in the equation,

Area of the rectangle= L* w

On expanding;

=x(x-5)+3(x-5)
=(x+3)(x-5)
The width is (x-5)
