Answer:
   x ∈ {-26, 22}
Step-by-step explanation:
A graph shows that the points (-26, -27) and (22, -27) lie on a circle of radius 40 centered at (-2, 5). That is, if Q is either one of these points, the vector PQ will have a length of 40:
- √((-26-(-2))^2 +(-27-5)^2) = √((-24)^2 +(-32)^2) = √1600 = 40
- √((22 -(-2))^2 +(-27 -5)^2) = √(24^2 +(-32)^2) = √1600 = 40
You can call it -40 if you like, but you have to define what negative length means when you do that.
 
        
             
        
        
        
Plug in the point
1 = 10 - 4(6)
1 = 10 - 24
1 = -14, false
Solution: B

8^2-6^2=28
the square root of 28 is 5.29
5.29×2=10.58
x=10.58
