<span>9c+(8+3c)
9c+8+3c (collect like terms)
9c+3c+8
12c+8
12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:
12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)
4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
</span>
All the answers are on the image attached. there is no work cause i did mental math. the answer to the riddle is typed in yellow at the bottom of the picture
8^2 + 5^2 = 64+25 = 89 = square root 89
