X squared + 8 squared = 10 squared
X= 6... answer B
4b^2 - 16 =
4(b^2 - 4) =
4(b + 2)(b - 2)
Step-by-step explanation:
Equation : (x - 4)² + (y + 3)² = 4.
Let
A-----> 
B-----> 
C-----> 
we know that
Point A-------> Multiply numerator and denominator by 

Point B-------> Multiply numerator and denominator by 

Point C-------> Multiply numerator and denominator by 

Find the distance Point A to Point C

Find the distance Point B to Point C

therefore

Point B is closer to Point C
is closer to 
the answer is
is closer to
