Answer:
Some real numbers are integer 
Step-by-step explanation:
 Real numbers ;
-  Natural numbers (counting numbers) = Integer 
-  Whole numbers = Integers
-  Integers =Integers 
- Rational numbers (fractions , repeating or terminating decimals) = Fraction and decimal are not integers 
- Irrational numbers. = Not integer
 
        
                    
             
        
        
        
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.
