Answer:

3

Step-by-step explanation:

All we need to do here is plug in the number 4 for the variable x. Wherever there's an x, kidnap it and replace it with a 4!

[tex]\frac{x + 20}{x + 4}[/tex]

x = 4

[tex]\frac{4 + 20}{4 + 4}[/tex]

Do the addition.

4 + 20 = 24

4 + 4 = 8

[tex]\frac{24}{8}[/tex]

We can simplify this! What is 24 divided by 8?

24/8 = 3

The answer is 3!
