Si la suma de 3 números enteros consecutivos es igual a p , ¿cual de las siguientes afirmaciones es siempre verdadera respecto al valor de p?

4. \( \left(6 x^{4}+8 x^{3}+5-2 x\right)+\left(3 x^{2}-7 x^{3}+8 x\right)= \)

4) Which of the following represents the correct factorization of \( x^{2}+7 x+10 \) ? A. \( (x+5)(x+2) \) B. \( (x+10)(x+1) \) C. \( (x+6)(x+5) \) D. \( (x+7)(x+3) \)

7. Use elimination and back-substitution to solve the following system of linear equations. \[ \begin{array}{c}x-y+z=0 \\ 3 x+y-3 z=0 \\ 2 x-2 y+2 z=0\end{array} \]

Write the expression as a single logarithm. \[ 6 \log _{b}(5 z+1)+\frac{1}{5} \log _{b}(z+9) \] \( \log _{\square}(\square) \)
