−30t10+45t4

Answer 1

To use the Distributive Property to multiply the polynomial \(-5t^3(6t^7 - 9t)\), we will distribute \(-5t^3\) to both terms in the parentheses.

1. Multiply \(-5t^3\) by \(6t^7\):
\[
-5t^3 \cdot 6t^7 = -30t^{3+7} = -30t^{10}
\]

2. Multiply \(-5t^3\) by \(-9t\):
\[
-5t^3 \cdot -9t = 45t^{3+1} = 45t^{4}
\]

Now, combine the results from both multiplications:
\[
-30t^{10} + 45t^{4}
\]

So the final result is:
\[
-30t^{10} + 45t^{4}
\]

This matches the response:
**−30t10 + 45t4 (negative 30 t superscript 10 baseline plus 45 t superscript 4 baseline)**.
