Step-by-step explanation:
Please can u put the graph... By the way the perimeter is the sum if sides 
 
        
                    
             
        
        
        
Answer:
34
first of all use formula:
n(AUB)=n(A)+n(B)-n(AnB)
 
        
             
        
        
        
Under box 36x + 9, Drag the following:
A.) 9(4x + 1)
D.) (9 . 4x) + (9 . 1)
Under box 9(4x - 1), Drag the following:
B.) (3 . 12x) - (3 . 3)
C.) 36x - 9
Under box (4 . 9x) + (4 . 2), Drag the following:
E.) 4(9x + 2)
F.) 36x + 8
Hope this helps!
        
             
        
        
        
One Way:
We can change the mixed number to a decimal for comparing.

 m = 

 m = 1.25 m
1.4 m     >    1.25 m
Darren   >     Luke
Darren's jump was higher by (1.4-1.25) 
0.15 m
Or another way change the decimal to a fraction and the mixed to an improper fraction too.

 = 

 (Luke)
1.4 = 

                               (Darren)
We need a common denominator to compare

       (Luke)

       (Darren)

          (Luke)

          (Darren)

        Darren           >            Luke  
By:

 - 

 = 

Which is also by 
0.15 m
Darren jumps higher and by 0.15 m
 
        
        
        
<span>You need to look at the scale of different values and find one which is in the 40th percentile. This means 40 percent are higher and 60 percent are lower than the value you select. This can be done by figuring out the middle and going up a bit.</span>
