Answer:
Option 2
Step-by-step explanation:
First distribute 5r to 2r and 4 to get 10r^2+20r
Then distribute 8 to 2r and 4 to get 16r+32
After that you combine the like terms, so combine 20r and 16r to get 36r
Since there aren't other like terms for 10^2 and 32 you leave them how they are
After you combine your like terms you write the terms in order to get 10r^2+36r+32
