What is the output of the function when the input is 0?

equation: 4x + 4 = 40

x = 9

Step-by-step explanation:

Given information:

• The perimeter of a square = 40

• Each side = x + 1

A square has 4 sides, and since each of the side lengths = x + 1, the perimeter is equal to 4(x + 1).

So, the perimeter is equal to 4x + 4, which is also equal to 40.

The equation that can be made to solve for x  is 4x + 4 = 40.

Now, to solve the equation:

4x + 4 = 40     Subtract both sides by 4 to isolate the variable.

4x = 36           Divide both sides by 4 to get the value of x.

x = 9

The value of x in this equation is x = 9.
