Answer:
The correct answer is A.
Step-by-step explanation:
The area of a rectangle can be calculated using the following formula: 

If we know that the area measures  and one side of the figure measures 4.2 m, we can say that:
 and one side of the figure measures 4.2 m, we can say that: 

We isolate the side we don't know: 

So I = 9 m
To know the perimter of a rectangle, we use the following formula: 



 
        
             
        
        
        
Answer:
Step-by-step explanation:
A linear graph with y values (height of tree) going up 2.5 with each increase of x (growing season)
This is the model that best fits the graph describing a growth of a plant
 
        
             
        
        
        
For this case we must find the quotient of the following expression:

By definition of power properties we have:

Rewriting the expression we have:

By definition of multiplication of powers of the same base we have to put the same base and add the exponents:
