Given:
_________________________________________________________

;

Solve when:  "n = 3" ; 

Rewrite the expression; substituting "3" for all values of "n" ; as follows:

  →   ; 

The "6" cancels out to "2" ; & the "3" cancels out to "1" ; 

→  {since:  " {6 ÷ 3 = 2}" ; and since:  " {2 ÷ 2 = 1}" .
_________________________________________________________
→  Since the "denominator" is "1" ; and any value, divided by "1";  results in that original value;  we can eliminate the denominator.

→  Now, we can rewrite the expression as:
_________________________________________________________
     →  "  2(3² + 2)"  ; 

            =  2(9 + 2) ; 

            =  2(11) ;

            =  " 22 " .

  →  The answer is:  " 22 " ;   which is:  Answer choice:  [B]:  " 22 " .
