If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way
Answer:
(x+1)(x²-4x+1)
Step-by-step explanation:
f(x) = x³-3x²-3x+1
= (x³+1) - 3x (x+1)
= (x+1)(x²-x+1) - 3x(x+1)
= (x+1)(x²-x+1-3x)
= <u>(x+1)(x²-4x+1)</u>
<u />
** (x+1)(x²-4x+1) = (x+1)((x-2)² - 3)
= (x+1)((x-2)² - (√3)²)
= (x+1)(x-2-√3)(x-2+√3)
The answer should be; 729 cm^3
