Answer:
Option (3)
Step-by-step explanation:
If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.
(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)
= -2x³ + x² + 9x + 12x² - 6x - 54
= -2x³ + 13x² + 3x - 54
Therefore, Option (3) will be the correct option.
Answer: $252
Explanation: First off, we want to do 450(0.7). The reason we do this is because the problem says she uses 30% of her money, meaning it goes down by 30%, not that the amount of money becomes 30% of what it originally was. 450(0.7) = 315. Next, we want to do 315(0.8) because it says she uses 20% of the REMAINDER. 315(0.8) = 252, and once you label it, it will become $252.
