Ihave a 92% in my class and that is a b in my school how many points to get an a which is a 94%-99% i really need an a

I would recommend
- studying maybe a week before the test so you can prepare for longer instead of waiting until the last minute
- Doing all homework
- Doing all classwork
- Participate in class
- Take all bonus opportunities
- Ask questions

Hope that this helps and all goes well with your grade!

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
