what is the product? -9x(5 - 2x) 18x² - 45x -18x² - 45x -18x - 45x 18x - 45x

Explanation:

Step1: Apply distributive property

$-9x(5 - 2x)=(-9x)\times5+(-9x)\times(-2x)$

Step2: Calculate each product

$(-9x)\times5=-45x$ and $(-9x)\times(-2x)=18x^{2}$

Step3: Combine results

$18x^{2}-45x$

Answer:

$18x^{2}-45x$
