To determine which expression is NOT equivalent to \((3x(4))(0)\), we can simplify this expression first. The expression involves multiplying by zero, which results in zero. Thus:

\[ (3x(4))(0) = 0 \]

Now, let's evaluate each of the given responses to see if any do not simplify to zero.

  1. \(3x(2)/3x\cdot x\):

    • This simplifies to \((3x^2)/(3x^2) = 1\) (assuming \(x \neq 0\)). This does NOT equal zero.
  2. \(3x(2)\cdot(1/3)x(−2)\):

    • This simplifies to \(3x^2 \cdot (1/3)x^{-2} = x^2 \cdot x^{-2} = 1\). This does NOT equal zero.
  3. \(x(4)\cdot0x(3)\):

    • This expression involves \(x^4 \cdot 0\cdot x^3 = 0\). This DOES equal zero.
  4. \((974x(12)y)(0)\):

    • This expression involves multiplying by zero: \( (974x^{12}y) \cdot 0 = 0\). This DOES equal zero.

From these evaluations, the expressions \(3x(2)/3x\cdot x\) and \(3x(2)\cdot(1/3)x(−2)\) both simplify to \(1\) and are therefore NOT equivalent to zero.

Conclusion: Any of the first two options is NOT equivalent to \((3x(4))(0)\). If only one choice must be picked, you could choose:

\(3x(2)/3x\cdot x\) as a response.
