If f (x) = 5 x minus 25 and g (x) = one-fifth x + 5, which expression could be used to verify g(x) is the inverse of f(x)?

Step-by-step explanation:

Given a certain function , and then its inverse function , the following expression is valid:

where the expression

indicates the composite function.

In this problem, we have:

And then, its inverse function is

To verify that g(x) is the inverse of f(x), the following expression must be true:

Substituting the expression of g(x) into f(x), we find that:

So, g(x) is the inverse of f(x).

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

it would open into a square depending on the type of envelope i’m not sure about the second part
