x-3

Step-by-step explanation:

The area of the flagpole base is $x^2-6x+9\ \text{yd}$

where the factor of the equation is the length of the base.

In order to find the length we need to factorize the equation

x^2-6x+9

=x^2-3x-3x+9

=x(x-3)-3(x-3)

=(x-3)(x-3)

The length of the base of the flagpole is $(x-3)\ \text{yd}$ .

10,648

Step-by-step explanation:

The total number of residents is 24,200.

The probability that a resident is from the central region is 0.44.

To find the number of residents in the central region, we multiply the corresponding probability by the total number of residents.

The number of people who live in the central region is

$=0.44\times 24,200$

=10,648
