Answer: 5x^2 - 3y^2 - 2xy +4
Step-by-step explanation:

Hello there!
Now, the formula to find the circumference of a circle is C = 2

r. Now, since the circumference is 18

, all we have to do is to divide 18 by 2 to find the <em>radius!</em>
The radius of the circle is 9 cm, since 18/2 = 9. However, this is the radius. We need the diameter.
Multiply 9 by 2 to find the diameter. 9 · 2 = 18. So
the answer is B. 18 centimeters.
Hope this helped!

Answer:
Open circle. Points right
Step-by-step explanation:
The reason for it is because this symbol > represents greater than when it comes to inequalities. When it is an open circle that means that you are not including the number. So that also means that the -2.5 is not included to the inequality equation but it can be any other number other than that number.
