What is the perimeter of the parallelogram?
units

36

Step-by-step explanation:

Find the slanted side by thinking of it as the hyptenuse of a triangle with sides 5 and 12

c² = 5² + 12²

c² = 25 + 144

c² = 169

c = 13

Perimeter

p = 2(5 + 13)

p = 2(18)

p = 36

i dont know sorry

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.
