Answer:
The length would be 10ft and the width would be 8ft
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 2 since we know it is 2 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width. 
P = 2l + 2w
36 = 2(x + 2) + 2(x) 
36 = 2x + 4 + 2x
36 = 4x + 4
32 = 4x
8 = x
Now since we know that the width is 8ft, we can add 2ft to it to get the length, which would be 10ft. 
 
        
             
        
        
        
Answer:
84 cubic feet
Step-by-step explanation:
First, multiply the numbers to get the volume.
5 2/5 * 4 2/3= 25 1/5
25 1/5 * 4 4/9= 112
Then, we can find 3/4 of that.
112*3/4=84.
 
        
                    
             
        
        
        
Answer:
Ari has 14 pennies.
Step-by-step explanation:
                            Number             Value             Total value
Pennies                  p                      $0.01                  0.01p  
Nickels               (22 - p)                $0.05             $(22 - p)0.05  
Total                       22                        -                      $0.54
Since Ari has total value of the coins = $0.54
0.01p + (22 - p)0.05 = 0.54
0.01p - 0.05p + 1.1 = 0.54
-0.04p = -0.56
p = 
p = 14
Therefore, total number of pennies Ari has = 14
