Answer:
Option C is correct.
![38 miles](https://tex.z-dn.net/?f=38%20miles)
Step-by-step explanation:
Let x be the distance cover by Michelle
Given:
A circle diameter is 3 miles.
And Michelle biked around the trail 4 times.
We know that
The circumference of a circle.
circumference =
----------(1)
where ![r=\frac{Diameter}{2}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7BDiameter%7D%7B2%7D)
miles
Put
and r value in equation 1.
![circumference = 2\times 3.14 1.5](https://tex.z-dn.net/?f=circumference%20%3D%202%5Ctimes%203.14%201.5)
![circumference = 9.42 mil;es](https://tex.z-dn.net/?f=circumference%20%3D%209.42%20mil%3Bes)
The circumference of a circle is 9.42 miles.
And Michelle biked 4 times, that is equal to 4
circumference.
![x = 4\times 9.42](https://tex.z-dn.net/?f=x%20%3D%204%5Ctimes%209.42)
.
That is equal to 38 miles.
Therefore, Michelle biked around 4 trail is 38 miles.

Answer:
(-8x+7y)(−8x+7y)+(2x-2y)(2x−2y)= simplified - 68x^2+53y^2−120xy
I hope this helps ! <3
Step-by-step explanation:
Answer: No she is not.
Step-by-step explanation: The correct answer is 7.25 F, because she just put them both as positives. When you have a negative it takes away from the total, so how I think of it is you subtract from the positive number, so you could just do 11.75-4.5. Hope this helped!
