A rectangle has a length of (5r+8) inches and a width of (2r + 4) inches. What is the area of the rectangle? Option 1: 10r^2 - 36r + 32
Option 2: 10r^2 + 36r + 32
Option 3: 10r^2 + 32
Option 4: 10r^2 - 32

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

Hope this helped!

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
