Answer:
the width of yuns area model is either 7x or (x - 2).
Explanation:
Since yun is trying to factor 7x² - 14x and the greatest factor is 7x.
Thus,he will get;
7x(x - 2)
Now,since he made an area model. The area of a rectangular model is:
Area = Length x Width.
Now, let's compare this area with the factorization of yun.
We'll see that;
The length is either 7x or (x - 2)
Similarly, the width is either 7x or (x - 2).
Thus, the width of yuns area model is either 7x or (x - 2).
