What is the perimeter of 5x^2 - 7x + 2. P = 2L + 2W

You have to substitute in the dimensions (length and width) from the problem above

The given expression 5x^2 - 7x + 2 does not represent the length and width of a shape. Therefore, it is not possible to calculate the perimeter using the formula P = 2L + 2W.
