Arectangle has an area of 45x2 − 42x − 48 and a width of 5x − 8. what is the length of the rectangle?

units.

Step-by-step explanation:

We have been given that a rectangle has an area of and a width of . We are asked to find the length of the rectangle.

Since we know that area of a rectangle equals to the product of its width and length, so to find the length of our given rectangle we will divide area of the rectangle by its width.

Upon cancelling from numerator and denominator we will get,

Therefore, the length of the rectangle is units.
