Answer 1

Х(х+6)>0 Х=0 или х=-6 Х^2+6х-7<0 (х-1)(х+7)<0 Х=1 х=-7 Дальше чертишь луч или таблицу. Получаешь (-7;-6)&(0;1)

Answer 2

It looks like you've provided an equation for which you need assistance. The equation you've given is "0 < 2x + 6x < 7." Let's break this down step by step.

Solving the Inequality:

To solve the inequality "0 < 2x + 6x < 7," we can simplify it by combining like terms first.

First, we simplify the middle part of the inequality: 2x + 6x = 8x

So, the inequality becomes: 0 < 8x < 7

Now, we can solve for x by isolating it. We'll start by dividing the entire inequality by 8:

0/8 < 8x/8 < 7/8 0 < x < 7/8

Conclusion:

So, the solution to the inequality "0 < 2x + 6x < 7" is 0 < x < 7/8. This means that x can take any value between 0 and 7/8, not including 0 and 7/8 themselves.
