How the heck r u supposed to round this? i tried and it says its wrong!

The result of division is 21.392

Rounded to the nearest tenth its  21.4  answer

(because the hundredth digit  is 9 so you add 1 to the tenth digit.)

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
