Answer:
A. x-6
Step-by-step explanation:
Maybe you want to simplify ...
((6x)/(10x^2))/(6/(10x^3 -60x^2))
Invert and multiply. Cancel common factors from numerator and denominator.
[tex]\dfrac{\left(\dfrac{6x}{10x^2}\right)}{\left(\dfrac{6}{10x^3-60x^2}\right)}=\dfrac{6x}{10x^2}\cdot\dfrac{10x^3-60x^2}{6}=\dfrac{6\cdot10x^2}{6\cdot10x^2}(x-6)\\\\=\boxed{x-6}[/tex]
