Final answer:

To solve the inequality [2+2w]-4>6, subtract 4 from both sides and remove the absolute value brackets by considering two cases. The solution in set notation is w > 4 or w < -6.

Step-by-step explanation:

To solve the inequality [2+2w]-4>6, we can start by subtracting 4 from both sides of the inequality:

[2+2w]-4-4 > 6-4

This simplifies to:

[2+2w] > 10

Next, we can remove the absolute value brackets by considering two cases:

Case 1: If 2+2w is positive, we simply have 2+2w > 10. Solving this inequality gives:

2+2w > 10

2w > 8

w > 4

Case 2: If 2+2w is negative, we have -(2+2w) > 10. Solving this inequality gives:

-2-2w > 10

-2w > 12

w < -6

Combining the solutions from both cases, the solution in set notation is:

w
