Answer: The answer is  
 
Step-by-step explanation:  Given in the question and the figure a large rectangle consisting of 12 squares of equal areas. We need to choose the right expression for the purple shaded area.
Considering the rectangle in the figure horizontally, there are 4 rows of 3 squares. So, in the last row, the fraction of  purple shaded square is

And if consider the figure vertically, then there are 3 columns of 4 squares. 
Therefore, the final fraction represented by the purple shaded area is

Thus, the correct option is   
 
 
        
                    
             
        
        
        
Answer:
 x^2 +4x -4
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
f(x) + g(x) = 4x+1 + x^2 -5
                = x^2 +4x -4
