Answer:
3(4+x)
Step-by-step explanation:
Three is the common factor in both 12 and 3x.
So, you remove that Togo outside the brackets.
What goes inside the brackets depends on the values remaining after you divide 3 from both
So 12 becomes 4
And 3x becomes x
There is a positive sign between them, because in this expression, the positive or negative is not affected Rut to the division.
Hope this helps.
Good Luck
