Foil (x-1)(x-1)(x-1) gives you x^3-3x^2+3x+1
(<span>x^3-3x^2+3x+1)(3X-3) foil
</span>gives you 2x^4-9x^3+15x^2+11x-3
for the other side
(x-1)(x-1)= x^2-2x+1
(2x+1)(x^2-2x+1) = 2x^3-3x^2+1
(2x^4-9x^3+15x^2+11x-3) - (<span>2x^3-3x^2+1)
</span>=2x^4-11x^3+18x^2+11x-4
Step-by-step explanation:
move the 27 to the other side of the equation like this
use this equation and substitute it into the y value of the first equation
Answer:
I am a bit confused on what the question is asking. But 64*186= 11904 and if we were to round that number it would be 12000. 21*98=2058 and that number rounded is 2100 or just 2000. (hope this is right and helps :D)
