Arectangle with a perimeter of 19m^2+2m-10 and a width of m^2 write an expression for the lenght

Step-by-step explanation:

By definition, the perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.

If you solve for "l":

In this case, you know that the following expression represents  the perimeter of the rectangle:

And the width of that rectanle is represented wih this expression:

Therefore, based on the explained above, you can conclude that the lenght  of that rectangle is given  by:

Finally, simplifying the expression, you get:
