Hi,
7x²-2x-8=0, so a = 7, b= - 2, and c = -8.
You just need to apply the formula for square equations:

Green eyes.
If the diameter of this circle is .96, then the radius is .48. The h and k values of our center are (-2, 5), and the standard form of a circle is

. We will fill in accordingly.

. That simplifies to

. That's the equation of the circle that will completely enclose the quarter.
Answer:
10
Step-by-step explanation:
the absolute value of a number is the distance from 0
the answer will ALWAYS be positive ;)
Answer:
whts the question??
Step-by-step explanation:
The radius of a circle is half the length of the circumference.
So multiply 12 by itself and you get 24.
The answer is C.
