The sum of polynomials involves adding the polynomials
The other polynomial is 
The sum of the polynomials is given as:

One of the polynomials is given as:

Represent the other polynomial with Q.
So, we have:

Q is congruent to P because they’re both got the same x and y number the x is 5 and -5 and for y is 3 and -3.
Answer:
Step-by-step explanation:
Divide 157 by 8 to see how many groups there are.
157/18=8r13. So you can round up to 9 groups of riders as there is a max of 18 at a time.
The one that best applies here is the b option: The range only includes numbers greater than or equal to 0. This is because<span> when you square a number that is negative or positive, it becomes a positive</span>
