Answer: The expression would be written as:

" 2(x + 8) " .
______________________________________________________
The expression could be further simplified.
______________________________________________________
Note the "distributive property" of multiplication:
______________________________________________________ a(b + c) = ab + ac ;

a(b – c) = ab – ac .
__________________________________________

__________________________________________
2(x + 8) = 2*x + 2*8 = 2x + 16 .
__________________________________________
The simplified version is: " 2x + 16 " .
