Answer:
She forgot to flip the sign in the last step.
Step-by-step explanation:
In inequality, if you multiply or divide by a negative number, you would have to reverse the inequality sign.
Marice forgot to do this in the final step. She had to divide '-8' to get x completely on one side. All other steps are correct.
The correct answer is x ≥ -1.
Hope this helps.

Answer:
The length of the original rectangle is 14 meters and the width of the original rectangle is 12 meters
Step-by-step explanation:
Let
l ----> the length of the original rectangle
w ----> the width of the original rectangle
we know that
----> equation A
----> area of a square
Solve for w
square root both sides
![(w+2)=(+/-)14](https://tex.z-dn.net/?f=%28w%2B2%29%3D%28%2B%2F-%2914)
![w=14=(+/-)14-2](https://tex.z-dn.net/?f=w%3D14%3D%28%2B%2F-%2914-2)
![w=14=14-2=12\ m](https://tex.z-dn.net/?f=w%3D14%3D14-2%3D12%5C%20m)
-----> this solution not make sense
so
![w=12\ m](https://tex.z-dn.net/?f=w%3D12%5C%20m)
Find the value of L
therefore
The length of the original rectangle is 14 meters and the width is 12 meters

Answer:
Step-by-step explanation:
This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.
