Answer:
16
Step-by-step explanation:
f ( x ) = 3x² - 2x
To find : f ( - 2 )
f ( - 2 ) = f ( x )
Here,
x = - 2
f ( - 2 ) = 3 ( - 2 )² - 2 ( - 2 )
            = 3 ( 4 ) - 2*( - 2 )
            = 3*4 + 4
            = 12 + 4
f ( - 2 ) = 16
 
        
             
        
        
        
7/10 as hundredths decimal: .07
7/10 as fraction: 7/100
 
        
             
        
        
        
When you do the inverse operation which in this case would be subtraction you do  54-17 and then you do 17 minus 17 which leaves you with the variable 54-17=34 so k=34
        
                    
             
        
        
        
Answer:
 total surface area of cone is πr (r+l)
 22/7 x 3 (3+4)
22/7*3 (7) 
22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket) 
hence,
TSA of cone = 66pi
