(x^7+5x^4-x+2)-(5x^4-x^3+2)
=x^7+5x^4-x+2-5x^4+x^3-2
Combining like terms
x^7+5x^4-5x^4+x^3-x+2-2
=x^7+x^3-x is your final answer. Hope it help!

The ration of radius of large cylinder (R) to that of the smaller cylinder (r) is

$\frac{18}{12} \\\frac{3}{2}$

Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is

$\frac{30}{20} \\\frac{3}{2}$

The scale factor is $\frac{3}{2}$
