in brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
