D. $ 3x30
Since $2.87 round to $3 and 27 rounds to 30 you would multiply the cost of each bag ($3) by the amount of people (30) meaning your estimate would be 30x3 which equals $90
Yes it’s the right answer, I just did it myself and I got -4
Yes. 6/4 is equivalent to 1 1/2 so 3 > 6/4
Answer:
Step-by-step explanation:
f(x) = x^3 - 6x^2 + 11x - 6
By the Rational Roots theorem, the roots will be among ±1,2,3,6
So try the low-hanging fruit first. It is clear that f(1) = 0. So, factoring that out, you have
f(x) = (x-1)(x^2-5x+6)
Now factor the quadratic in the usual way.
