Answer
$(-2,\infty)$
Work Step by Step
Step 1. Rewrite the inequality as $\frac{7}{x+2}-\frac{1}{x+2}\ge0$ or $\frac{6}{x+2}\ge0$
Step 2. Identify the boundary point as $x=-2$
Step 3. Use test points at $x=-3, 0$, the signs of the left side are $-, +$
Step 4. The inequality requires positive (right regions, excluding $x=-2$), thus the solution intervals are $(-2,\infty)$
