Simplify the following expression (x+3) (x+5)

2x+8

Step-by-step explanation:

Here, you have to find the similar sides. x and x are both the same thing, while 3 and 5 are both integers (whole numbers).

You add the similar sides together, then that is your answer.

x + x = 2x, and 3+5 = 8.

Note: Just because I said that x and x are the same doesn't mean that you can just add random numbers together in other questions.
