There are no like terms.
Answer:

The model will be 5 times longer that stated.

Step-by-step explanation:
:))
like ex.
2 4 6 8 10 12
For perimeter you can find it 2 ways:
l=length, w=width
(2)l+(2)w=perimeter
or just:
l+l+w+w= perimeter
Hope this helps!!!
In a normal distribution, the z value for an x value that is to the right of the mean will always be positive while on the other hand if the z value for an x value that is to the left of the mean it will always be negative. It is because left side is always negative and right side is always positive.
