Answer:
![-2 \geq w \geq 2](https://tex.z-dn.net/?f=-2%20%5Cgeq%20w%20%5Cgeq%202)
Step-by-step explanation:
Given
![|-w| \geq 2](https://tex.z-dn.net/?f=%7C-w%7C%20%5Cgeq%202)
Required
Solve for w
![|-w| \geq 2](https://tex.z-dn.net/?f=%7C-w%7C%20%5Cgeq%202)
In absolution functions;
![|-w| = |w|](https://tex.z-dn.net/?f=%7C-w%7C%20%3D%20%7Cw%7C)
So, the given expression can be rewritten as
![|w| \geq 2](https://tex.z-dn.net/?f=%7Cw%7C%20%5Cgeq%202)
Removing the absolute sign, will gibe
or ![w \leq -2](https://tex.z-dn.net/?f=w%20%5Cleq%20-2)
When the second inequality os rewritten, it gives
or ![-2 \geq w](https://tex.z-dn.net/?f=-2%20%5Cgeq%20w)
Reorder both inequalities
or ![w \geq 2](https://tex.z-dn.net/?f=w%20%5Cgeq%202)
Lastly, both inequalities are combined
![-2 \geq w \geq 2](https://tex.z-dn.net/?f=-2%20%5Cgeq%20w%20%5Cgeq%202)
Harrison walked a total of 14 km because the first rectangle has a perimeter of 6 km and the second has a perimeter of 8 km. Harrison’s brother walked a total of 12 km since that was the perimeter of the 5*1. 14-12 is 2 so there is a 2 km difference.
Answer:

Here is the way to find percentage.
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
