f(x)= 9x^3+ 2x^2 -5x+ 4
g(x)= 5x^3 -7x+ 4
f(x) - g(x)
= (9x^3+ 2x^2 -5x+ 4) - (5x^3 -7x+ 4)
= 9x^3+ 2x^2 -5x+ 4 -5x^3+ 7x -4
= (9x^3 -5x^3)+ 2x^2+ (7x -5x)+ (4-4) (combine like terms)
= 4x^3+ 2x^2+ 2x
= 2x* (2x^2+ x+ 1)
The final answer is 2x* (2x^2+ x+ 1).
900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8

Answer:
4 kg : 12 kg : 20 kg
Step-by-step explanation:
The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...
(36 kg)/9 = 4 kg
Multiplying the given ratio by 4 kg will show the appropriate division:
1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg
X=10 is the answer to this
