The pentagon shown has 5 equal sides. The side lengths are represented by the expression 9k+4. What is the perimeter?

5(9k+4)

45k+20

Step-by-step explanation:

You could add all the sides together or use distributive property and multiply the one side length by 5

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
