Sarah wants to install new carpet in her living room. The small square is tiled and will not be carpeted. How many square yards of carpet will she need?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
