Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is 
.
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with is 
, where r is the radius.
We get 
take square root of both sides.
Hence radius of the given circle is r = 2.
Answer:
2.
4x^2 + 4 - 5x + x - 2x^2 + 8
= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)
= 2x^2 - 4x + 12
=> D is correct
3.
2x^2 + 6x - 7x + 8 - 3x^2 + 1
= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)
= -x^2 - x + 9
=> C is correct
4.
B is correct (4 and 3)

The answer would be C (17/6)
This is because;
6 goes into 17 twice leaving a reminder of 5.
The addition property of equality. It says that if you add the same number to each side of the equation, the two sides of the equation will be equal. In this case, the number 8 was added to each side.
Hope this helps :)
If at least one has to be heads then it would be 1/5
