In a compound inequality, "and" indicates that both conditions must be true simultaneously for the overall statement to be true. For example, in the inequality (x > 2 \text{ and } x < 5), (x) must be greater than 2 and less than 5 at the same time. Conversely, "or" means that at least one of the conditions must be true. For example, in the inequality (x < 2 \text{ or } x > 5), (x) can be either less than 2 or greater than 5, satisfying the inequality.
No. This is not an inequality, because you need something > something_else, or less than or 'not equal' or 'greater than or equal', etc. Since it has an x cubed term, it is not a quadratic.
This compound inequality cannot be solved.

x < 2/3
If x represent the length then, 1000 < x < 2600
No. This is not an inequality, because you need something > something_else, or less than or 'not equal' or 'greater than or equal', etc. Since it has an x cubed term, it is not a quadratic.
'r' is equal to, or anywhere between, -13 and 38 .
You need to reverse the inequality symbol when multiplying both sides of an inequality by a negative number because you are changing the sign of both sides of the equation. Since inequality, such as "less than", means "to the left of" on the number line (where left is minus and right is plus) then a number that is less than another will be greater than the other if the signs were reversed. Example: 3 is less than 4, but -3 is greater than -4.
No. To be an inequality, it must somewhere have a greater than, less than, greater-or-equal, or less-or-equal sign.
