Step-by-step explanation:

for the square in the middle, 7x4=28

for the triangles on the left and right 7x5=35 and since there are two of them you dont need to divide by 2

for the triangles on top and bottom, 3x4=12 and also 2 of them so you dont need to divide by 2

then just add it all up

c is the correct answer

step-by-step explanation:

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.
