Answer:    7
Step-by-step explanation:
Here, two chords of the circle is intersecting outside the given circle.
Thus, By the intersecting chord outside the circle theorem,
 
 
 
 
 
 


Hence, the value of x is 7.
 
        
             
        
        
        
1. y= -x + 3 
2. y = x - 3
3. y = 3x + 1 
4. y = -3x - 3
        
             
        
        
        
Im pretty sure its a and c but if it cant be both of them then u or ur teacher probably wrote one of them wrong
        
                    
             
        
        
        
formula for volume of a sphere is V=4/3 x pi x R63
if diameter = 16 than radius = 16/2 = 8
 so the equation would be 4/3 x pi x 8^3
 
        
             
        
        
        
Apply the radical rule to separate terms:
Cubicroot(-27) and cubic root(n^27)
Cubicroot(-27) = -3
Now you have -3 cubicroot(n^27)
Using the exponent rule
N^27 can be rewritten as (n^9)^3
Now you have -3 cubicroot((n^9)^3)
The cubic root and the 3rd power cancel out to get the final answer of
-3n^9
