The base and height of a triangle are each extended 2 cm. what is the area of the shaded region?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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.
