3r + 2rt = 18
r is the common factor
r(3 + 2t) = 18
r= 18/ 3 + 2t
r= 6 + 9t
Hope this helps!

*Sorry I messed up my math please read the new answer.
Use distrubitive property to get rid of parentheses. Multiply -3 by 4r and -8 to get -12r+24=36. Then zero out 24 by subtarcting 24 from both sides. You. should then have -12r=12. Divide by -12 on both sides to get r by itself. Your answer should be r=1*. Hope this helps :)
The answer is D.
To get an area of any 4 sided object (like you text book) , we multiply the length and the width.
All the other answers don't multiply only 2 numbers together, so we know it must be D)
