The property of polynomial addtion that says that the sum of two polinomials is alwasy a polynomial is called closure property of addition or under addtition.
Polynomials are closed under addtiion because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polinomyal of the same kind, except for the terms that cancel (positve with negative) which does not change the fact that the result is still a poynomial.
In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

15
Step-by-step explanation:
Joyce reserved number 1 for herself
Of all the possible combinations,
1 and 15 is a perfect match for a perfect square
So,Joyce dinner partner was number 15.
Answer:
Neither
Step-by-step explanation:
It's neither. The terms do not differ (which means you add the same number to each term) by any constant amount. (Arithmetic)
The terms do not have a common number that you multiply the present term to get the next term. (Geometric)
So this one is neither.
To solve for the time it takes to travel a certain distance at a certain speed, use the formula,
time = distance / speed
Given that the entire journey takes four hours, add up the time it takes David to row upstream with that of him travelling downstream. This is mathematically represented as,
total time = time upstream + time downstream
4 = 3/(x - 1) + 3/(x +1)
Solving for x in the equation gives 2. Thus, David's speed in still water is 2 miles per hour.
