For this question, all we are going to do is plug all 5 of those numbers into the function f(x) = 3x.
The numbers we're given are {3, 4, 6, 7, 9} So lets plug them in!
3*3=9
3*4=12
3*6=18
3*7=21
3*9=27
So the answer is {9, 12, 18, 21, 27}! If you have any questions I'd be happy to help!
        
             
        
        
        
D. Sasha's method is exponential because it increases by a fixed factor, and Mona's method is linear because it increases by a fixed number.
Hope this helps!~
        
                    
             
        
        
        
Yes if he practices X amount of hours and is told to practice X amount of hours than he practiced long enough
        
             
        
        
        
Ok so find greatert common factor
ab+ac=a(b+c)
15x=3*5*x
9=3*3
gcf=3
15x-9=
3(5x)+3(-3)=
3(5x-3)
possible dimentions is 3 unit and 5x-3 units
        
             
        
        
        
That would be 2.1 because if it's in decimal it's 2.1
