Answer:
8x + 1
Explanation:
This is called "distributive property". What you do here is you take the number on the left outside of the parentheses (4) and you distribute it to the 2x and 1.
4 times 2x is 8x. 4 times 1 is 4. So what you would get is 8x + 1. You can simpify anymore then that so that would be your finale answer.
Hope it helped! If you need help lmk :)
