2_ / _ \ _x+2​

Answer 1

$> resolucao \\ \\ \geqslant \: teorema \: de \: tales \\ \\ \frac{4}{2} = \frac{x}{x + 2} \\ \\ 4x + 8 = 2x \\ 4x - 2x = - 8 \\ 2x = - 8 \\ x = - \frac{8}{2} \\ x = - 4 \\ \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$

Answer 2

Explicação passo-a-passo:

$\frac{x}{x + 2} = \frac{4}{2}$

$\frac{x}{x + 2} = 2$

$2.(x + 2) = x \\ 2x + 4 = x \\ 2x - x = - 4 \\ x = - 4$
