The scale model of a building is 5.4 feet tall. if the original building is 810 meters tall, what was the scale used to make the model?

true? is that what you're asking or do you mean something else?

(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
