I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)
        
                    
             
        
        
        
Answer:
a right angle
Step-by-step explanation:
The best and most correct answer among the choices provided by the question is the second choice "a right angle"The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."I hope my answer has come to your help. God bless and have a nice day ahead!
 
        
             
        
        
        
0 because the square root of zero is zero and two divided by zero is zero
        
             
        
        
        
Answer:
x≤17
Step-by-step explanation:
 
        
             
        
        
        
Simply take the numerator (3) and denominator (7) and add them together. 
3+7 = 10, which means that the ratio will provide parts that are in multiples of 10 depending on the total
so take 10x = 800 
x = 80.
Then multiply this by the numerator and denominator 
3*80/7*80 = 240/560.
