I believe the answer would be (1) because they are not directly related
Answer:

Step-by-step explanation:
See the attached picture for explanation.
Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).
However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).
In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
Answer:
3.3075 liters of paint
Step-by-step explanation:
7.40 (red paint) + 6.26 (blue paint ) = 13.66 (purple paint)
He pours 13.66 liters of purple paint equally into 4 containers and has 0.43 liters left.
x + x + x + x = 13.66 - 0.43
4x = 13.23
x = 13.23/4
x = 3.3075
