Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute 
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
 
        
             
        
        
        
Answer:
x=3
Step-by-step explanation:
10-3x+8x=25
-10            -10
-3x+8x=    15
5x=15
5x/5=15/5
x=3
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
 Find the x-coordinate of the vertex with this formula:
 
 In this case:
 
 Substituting values, we get:
  
 
 Now we can substitute the coordinates of the vertex into the equation  and then solve for "c".
 and then solve for "c".
 Then:
