Answer: Bottom left corner

Let n be an odd number. Because 4n is a multiple of 2, it is an even number.

============================================

Explanation:

The square has a side length of n, so its perimeter is 4n since n+n+n+n = 4n.

We can rewrite 4n as 2*2n = 2m where m = 2n is an integer. Any number in the form 2*(some integer) is always even. Even numbers always have 2 as a factor.

So whenever it comes to proving something is even, the ultimate goal is to get it into the form 2*(some integer). If we can do this, then the number is even. If not, then the number is odd.

What is the inverse of the function f(x) = x + 2?
nadya68 [22]

Answer: h(x)=x-2

Step-by-step explanation:

To find the inverse of the function f(x) = x + 2, the first  step is to replace f(x) with "y":

 f(x) =y= x + 2\\\\ y = x + 2

The second step is to solve for the variable "x":

x=y-2

The third step is to interchange the variables, then:

y=x-2

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

h(x)=x-2
