Answer:
C
Step-by-step explanation:
Let's simplify this expression first:
[tex]Line1: 3x+3(2x+4)-8\\Line2: 3x+6x+12-8\\Line3: 9x+4\\[/tex]
- In Line 2, we have used distributive property ([tex]a(b+c)=ab+ac[/tex]) and thus multiplication.
- In Line 3, we have combined like terms
Choices A, B, and D can be eliminated as we have done those to simplify the expression.
Thus, "evaluation" -- choice C is the correct answer for this question.
Evaluation is when we plug in a specific value in the variables to find a "value/answer" of the expression given.
