Answer:
After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes
.
Step-by-step explanation:
Given:

We need to arrange the terms of given Polynomial from highest to lowest.
Now on seeing the above polynomial we can say;
The terms of polynomial can be arrange according to the highest number of exponent.
Form above expression we can say the first highest exponent term is 
Hence the First term is
.
Now we can see the second highest exponent term is 
hence the second term would be
.
now we can see the third highest exponent term is 
hence the third term would be
.
now we can see the fourth term is 
hence the fourth term would be
.
Hence After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes 
We are asked to find for an expression that represents the perimeter of a picture frame which has a shape of a rectangle. The dimensions given are length of size x cm and a width of size 9 cm.
The formula for the Perimeter of a rectangle is given by
P=2L+2W
where L is the length and W is the width of the rectangle.
Hence,
P=2(x)+2(9)
Simplifying this values would give us a result of,
P=2x+18
Therefore, 2x+18 is the expression that represent the perimeter of the picture frame.
