Answer:
11x + 11
Explanation:
( 4x + 8 ) + ( 7x + 3 )
Remove parenthesis;
Note: Remember, the associate property states that if an equation is either all multiplication or addition, then it can be done in any order, hence the parenthesis holds no weight in this case.
4x + 8 + 7x + 3
Combine like terms;
11x + 11
