To use the Distributive Property to multiply the polynomial \(-5t^3\) with the expression \(6t^7 - 9t\), follow these steps:

  1. Distribute \(-5t^3\) to each term inside the parentheses:

    \[ -5t^3 \cdot 6t^7 + (-5t^3 \cdot -9t) \]

  2. Now, perform the multiplication for each term:

    • For the first term: \[ -5t^3 \cdot 6t^7 = -30t^{3+7} = -30t^{10} \]

    • For the second term: \[ -5t^3 \cdot -9t = 45t^{3+1} = 45t^{4} \]

  3. Combine the results:

    \[ -30t^{10} + 45t^{4} \]

Thus, the result of multiplying the polynomials is:

\(-30t^{10} + 45t^{4}\)

So the correct answer from your options is:

\(-30t^{10} + 45t^{4}\)
