<u>Step 1: Set up</u>
(9x² - 4x + 11) + (3x² - 2x + 2)
<u>Step 2: Simplify</u>
- Combine like terms (x²): 12x² - 4x + 11 - 2x + 2
- Combine like terms (x): 12x² - 6x + 11 + 2
- Combine like terms (Z): 12x² - 6x + 13
Answer:
30
Step-by-step explanation:
Ratios always remain proportionate. In this case, the simplified ratio has 1 red car. The question tells us that there are 6 cars. 6 is 6 times bigger than 1; thus showing that the ratio has increased by a factor of 6. If one side of the ratio increases by a factor of 6, then the other side must also increase by a factor of 6. Since 5*6=30, there must be 30 employees that own a black car.
