the area of a rectangular field is by the tronomial t^2-4t-45. the length of the rectangle is t +5. What is the expression for the width of the field
To find the expression for the width of the field, we need to divide the area by the length.
The area of the rectangular field is given by t^2-4t-45.
The length of the rectangle is t+5.
So, the width of the field can be found by dividing the area by the length: (t^2-4t-45)/(t+5).
Therefore, the expression for the width of the field is (t^2-4t-45)/(t+5).
