$\begin{array}{c|c}_{-}\ x^4+2x^2-24 &\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\! \underline{ x+2 } \\ \!\!\!\!\!\!\!\!\!\!\! \underline{x^4+2x^3}& x^3-2x^2+4x-8 \\{ \big{_{-}}}-2x^3-24& \\\underline{-2x^3-4x^2}& \\ _{-} \ 4x^2-24 & \\ \underline{4x^2+8x}& \\ _{-}-8x-24& \\ \underline{-8x-16} & \\ -8 &\end {array }$

$\displaystyle \frac{x^4+2x^2-24}{x+2} =x^3-2x^2+4x-8 -\frac{8}{x+2}$

Find the values of x work 10% of my grade

Ostrovityanka [42]

Answer:

x = 35

Step-by-step explanation:

1. Add all angles

$115+(x+36)+24+(2x+10)+2x$

= $5x+185$

2. Match 360 and fix

$5x+185=360$

$5x=360-185$

$5x=175$

$x=175/5$

$x=35$

Hope this helps
