Answer

None of these are true.

Steps

Step 1 ：\(9\) and \(4\) are not like terms.

Step 2 ：\((3x+8)\) is written as a sum of two terms, not three.

Step 3 ：In \(3x\), \(3\) is indeed a coefficient.

Step 4 ：In \((3x+8)\), \(3x\) is a term, not a constant.

Step 5 ：\(3x\) is a factor of the given expression.

Step 6 ：None of these are true.
