Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x
Hope this helps :)

You have not given us any of the steps that Ricardo took to simplify the 
expression, and you also haven't given us the list of choices that includes 
the description of his mistake, so you're batting O for two so far.  
Other than those minor details, the question is intriguing, and it certainly 
draws me in.
If Ricardo made a mistake in simplifying that expression, I'm going to say that
it was most likely in the process of removing the parentheses in the middle.  
Now you understand that this is all guess-work, because of all the stuff that you 
left out when you copied the question, but I think he probably forgot that the  3x  
operates on everything inside the parentheses.
He probably wrote that  3x (x-3)  is
either    3x² - 3
     or       x - 9x .
In reality, when properly simplified,
       3x (x - 3)  =  3x² - 9x .

Answer:
060.28
Step-by-step explanation:
3 can't go into 1, but it goes into 18 six times with 0 left over. 3 goes into 0 zero times. 3 goes into 5 one time with 2 left over. 3 goes into 26 (because you pull the 6 down) 8 times with 2 left over.
