Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result will be a polynomial.
Step-by-step explanation:
The set of all polynomials is <em>closed</em> under addition, subtraction, and <em>multiplication</em>, because performing any of these operations on a pair of polynomials will give a polynomial result.

<em>Comment on the question</em>
The wording is a bit strange, because f(x) and g(x) are elements of a set (of polynomials), so cannot be said to be "closed." "Closed" is a property of a set with respect to some function, it is not a property of an element of the set.
Answer:
answer is b
Step-by-step explanation:
So, 1725 would be 1 and a half month's pay of rent.
The equation would be 1725 divided by 1.5 since that would get us what the two friends paid for one month of rent. Let r= rent.
1725/1.5= r
1725/1.5= 1150
So, rent would equal $1150.
I hope this helps!

Answer:
A
Step-by-step explanation:
First step, convert liter to millimetres
1l - 1000mm
2.5 x 1000 = 2500 mm
2. convert mm to fluid ounce
2500 / 29.8 = 84
Y = 6x + 11....slope here is 6. A parallel line will have the same slope.
y = mx + b
slope(m) = 6
(-5,1)...x = -5 and y = 1
now we sub and find b, the y int
1 = 6(-5) + b
1 = -30 + b
1 + 30 = b
31 = b
so ur equation is : y = 6x + 31...but we need it in standard form
y = 6x + 31
-6x + y = 31 ...multiply by -1 to make the x term positive
6x - y = -31 <===
