Solve the polygon for x

wariber [46]

Octagon has sum of angles 1080°

$\\ \rm\Rrightarrow 5(10x+15)+2(14x)+6x-3=1080$

$\\ \rm\Rrightarrow 50x+75+28x+6x-3=1080$

$\\ \rm\Rrightarrow 84x+72=1080$

$\\ \rm\Rrightarrow 84x=1008$

$\\ \rm\Rrightarrow x=1008/84$

$\\ \rm\Rrightarrow x= 12$

Can someone help me? It's urgent and thank you!

Answer:

option A

Step-by-step explanation:

$\frac{x+ 3}{12x} \ \cdot \ \frac{4x}{x^2 +x - 6}\\\\= \frac{x+ 3}{12x} \ \cdot\ \frac{4x}{x^2 +3x - 2x - 6}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{x(x + 3) -2(x+3)}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{(x + 3)(x -2)}\\\\= \frac{1}{12x} \ \cdot \ \frac{4x}{(x - 2)} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\\\= \frac{1}{3} \ \cdot \ \frac{1}{(x - 2)}\\\\= \frac{1}{3(x - 2) }$
