Answer:

Step-by-step explanation:
Given polynomials are:
,
and 
Now we need to add the given polynomials, then place the answer in the proper location on the grid. Also we need to write answer in descending powers of x.
So let's add them by combining like terms:


Hence final answer in descending order is 
If you put 7% into a decimal it would be 0.07
There are only 6 place values in 128,955.
If you would round it it could be:
130,000
129,000
128,960
