Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,

x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.

Answer:
Step-by-step explanation:
Factor the polynomials.
x^2-4 = (x+2)(x-2)
x^2+5x+6 = (x+3)(x+2)
(x^2-4)/(x^2+5x+6) = (x+2)(x-2)/[(x+3)(x+2)] = (x-2)/(x+3)
