9. The area of a yard is given by the equation y = x2 – 12x + 32. If the

length of the garden is given by the expression x – 4, what is the width of

the yard?

The width of the yard is given by the expression (x - 8).

Step-by-step explanation:

We are given the following in the question:

Area of yard, y =

Length of garden =

We have to find the with of the garden.

Area of yard =

Putting the values, we get:

Now,

Thus, the width of the yard is given by the expression (x - 8).
