Answer:
(A) 37.7 feet
Step-by-step explanation:
It is given that there is a circular garden which has a diameter of 12 feet, therefore the radius of the garden will be:
![R=\frac{D}{2}=\frac{12}{2}=6 feet](https://tex.z-dn.net/?f=R%3D%5Cfrac%7BD%7D%7B2%7D%3D%5Cfrac%7B12%7D%7B2%7D%3D6%20feet)
Thus, radius of the garden is 6 feet.
Now the circumference of the circular garden will be:
![C=2{\pi}r](https://tex.z-dn.net/?f=C%3D2%7B%5Cpi%7Dr)
![C=2{\pi}(6)](https://tex.z-dn.net/?f=C%3D2%7B%5Cpi%7D%286%29)
![C=2(3.14)(6)](https://tex.z-dn.net/?f=C%3D2%283.14%29%286%29)
![C=37.7feet](https://tex.z-dn.net/?f=C%3D37.7feet)
Therefore, the circumference of the circular garden will be 37.7 feet.
Hence, option A is correct.
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
