Multiply and simplify: 10x (6x^2 + 7x + 9)

Question 4 options:

60x^3 + 70x^2 + 90x

60x^2 + 70x + 90

6x^2 + 17x + 9

60x^3 + 160x

If you would like to solve the following expression, you can calculate this using the following steps:

10 * x * (6 * x^2 + 7 * x + 9) = 10 * x * 6 * x^2 + 10 * x * 7 * x + 10 * x * 9 = 60 * x^3 + 70 * x^2 + 90 * x

The correct result would be 60 * x^3 + 70 * x^2 + 90 * x.
