<h3>What is the formula of unitary method?</h3>The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Given that,
Jasmine can run 4 miles in
of an hour.
of an hour = 4
miles
= miles
By using unitary method we will find the value of an hour.
1 hour =
= ×
=
1 hour = 7.25 miles
Hence, Jasmine can run in one hour is 7.25 miles.

Answer:
A
Step-by-step explanation:
An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.
For expression A
The denominator will be zero when x² - 4 = 0
x² - 4 is a difference of squares, thus
(x - 2)(x + 2) = 0
x - 2 = 0 ⇒ x = 2
x + 2 = 0 ⇒ x = - 2
The excluded values of x are x = ± 2 ⇒ A
