The list of choices is missing so I am going to give my wording:
The fact that a set closed under a certain operation means that when the operation is applied to any element(s) of the set, the result will be also an element of the same set (as opposed to something that does not belong to the set).
In this case the set contains all polynomials. Multiplying any two polynomials results in another polynomial, therefore this set is closed with respect to multiplication. In contrast, the set is not closed with respect to division. Dividing two polynomials may lead to non-polynomial expressions with non-integer powers and so the set is not closed under division.

Yo uneed to find the Area/volume
The area of the rectangle is 2×(5cm×1cm)+2(3cm×1cm)+2(5cm×3cm)=10cm+6cm+30cm=36cm^2
Volume=5cm×3cm×1cm=15cm^3
Ratio: 36cm^2/15cm^3=12cm^2/5cm^3
Answer:
a number that is substituted in an inequality that makes the inequality a true statement.
EXAMPLE :
x + 2 < 7 ; x= 4
1) substitute 4 into the inequality
4 + 2 < 7
2) solve ( add 4 and 2 together )
6 < 7
the number 4 is a solution to the inequality because 6 < 7 is true.
