To do this we need to combine like terms, meaning combine the terms that have the same variables.
b is one variable that can be combined:
-2b - 6 + 3b - 2
b - 6 - 2
Now, combine the digits:
b - 8
Hope this helped!
The answer is A.5% i am not 100% sure thooooo
A²+B²=C²
6²+8²=C²
C²=100
C=10
Therefore the length of AB is 10 units
The equation of a circle with center 
and radius 
is
In your case,
Plug these values into the generic formula and you'll get your equation.
