Step-by-step explanation:
Longest side is between 36 and 18 feet
18 < L < 36
IF longest side were 36 feet, width =0
IF longest side were 18, then width = 18
to be longest L>W L>18. and L can't be as much as 36 to keep width >0
 
        
             
        
        
        
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.<span />
        
                    
             
        
        
        
Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is  , then m=
, then m= . Since the y-intercept is -3, b=-3.
. Since the y-intercept is -3, b=-3. 
Then, we can create the equation: y= x-3
x-3
