36

Step-by-step explanation:

N^2 + 2N + 1

Since we are given N = 5, we just substitute N for 5

(5)^2 + 2(5) + 1

25 + 10 + 1

36

36

Step-by-step explanation:

5*5 + 5*2 +1 = 25 + 10 + 1 = 36

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

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.
