Answer:
see explanation
Step-by-step explanation:
since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
 
        
                    
             
        
        
        
You flip is when you mulitply the whole equation by a negative
not when you distribute a  negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3
but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x
  
because they will be differente
exaple
12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true 
anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole
        
             
        
        
        
The formula for the area of a circle is 

We know the diameter, and the radius is half of the diameter.  So the radius is 9.  Now we plug that into the formula.

So the answer is B, 81 pi square feet
 
        
        
        
Two ratioa that are equivalent to 9/12 are
3/4 
18/24
