Positive correlation means that if x goes up then y goes up, negative correlation means that if x goes up then y goes down.  Since both x and y are increasing each time, it is positive. 
        
             
        
        
        
Answer:
B) A/l
Step-by-step explanation:
Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other. 
Divide l from both sides of the equation: 
A = l * w
(A)/l = (l)/l * w
w = A/l
B) A/l is your answer.

If you divide 5 by 6 to turn it into a decimal, you get 0.83. All you have to do is find a numerator that you can divide by 8 to get a decimal less than 0.83. 
So, 1/8, 2/8, 3/8, 4/8, 5/8, or 6/8 would work.
        
                    
             
        
        
        
Answer:
144
<h3>
Step-by-step explanation:</h3>
If 48 is the perimeter, then 48 divided by 4 is one of the side lengths. 
L x W = Area 
12 x 12 = Area 
12 x 12 = 144
Area = 144
