What is the width of Averi's area model? (See picture)
shepuryov [24]

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,

\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}

x² + 5x - 4 = Width

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