Sqrt(x) - 5+7 =11
combine like terms
-5 +7 = 2
sqrt(x) + 2 = 11
subtract 2 from each side
sqrt(x) = 9
square both sides
x = 9^2
x = 81
an extraneous solution would be an invalid solution
in this case it is not an extraneous solution
Answer:
c = 3 oil changes
Step-by-step explanation:
The fixed rate for oil change is $ 40
The surplus rate for miles outside the radius is $ 2.25
Josh lives 7 miles of the radius
Therefore an equation for c: The largest number of oil changes that can be scheduled and maintained within the budget for the year is:
oil changes
Therefore, with the budget set Josh can make a maximum of 3 oil changes per year

Answer:
The answer is
<h2>660.5 square feet</h2>
Step-by-step explanation:
Area of a circle = πr²
where r is the radius
From the question
diameter = 29 feet
To find the radius given the diameter we use the formula

So the area of the circle is

We have the final answer as
<h3>660.5 square feet</h3>
