Solve the following system of equations by the addition method. It the system does not have a single ordered pair as a solution, state whether the system is inconsistent or dependent \( \begin{array}{l}6 x+4 y=-22 \\ 3 x-y=-17\end{array} \) What is the solution to the system of equations? Select the correct choice below and, if necessary, fill in the answer box to complete your choice A. The solution is \( \square \). (Type an ordered pair.) B. There are infinitely many solutions. The system is dependent. C. There is no solution. The system is inconsistent.

The polynomial of degree \( 4, P(x) \), has a root of multiplicity 2 at \( x=3 \) and roots of multiplicity 1 at \( x=0 \) and \( x=-1 \). It goes through the point \( (5,12) \). Find a formula for \( P(x) \). \( P(x)=\square \)
