To determine the value of the expression ( 6(1 + 2) - 4 ), you start by simplifying the expression inside the parentheses.
First, calculate ( 1 + 2 ), which equals ( 3 ). Next, replace the expression in parentheses with this value: ( 6(3) - 4 ).
Now, multiply ( 6 ) by ( 3 ), giving you ( 18 ). At this point, the expression is simplified to ( 18 - 4 ).
Finally, subtract ( 4 ) from ( 18 ), resulting in ( 14 ).
Thus, the correct result of simplifying the expression is not ( 16 ), but rather ( 14 ). The other answer choices are also not accurate based on the calculation conducted.
