None of these really do. The associative property is about regrouping things being added, such as
(3+5)+7 = 3+(5+7)

Someone could I guess argue the “4+2y+7x+8” used it, by dropping the parentheses and thereby changing the grouping to just be the standard left-to-right that the order of operations dictates. But that’s a pretty lame answer if that’s what the person is going for.

Given the inequality -8 < 2, explain what happens when you multiply or divide both sides by 2 and what happens when you multi

Answer:

The inequality sign remains same while multiply or divide both sides by positive numbers.

The inequality sign changes while multiply or divide both sides by negative numbers.

Step-by-step explanation:

The given inequality is - 8 < 2.

Now, if we multiply 2 in both sides then - 16 < 4

Again, if we divide by 2 into both sides then - 4 < 1

Therefore, the inequality sign remains the same while multiply or divide both sides by positive numbers.
