( (r+2) * (2r-9)-(r^2+17r+30) )/(r+2)
none of the parenthetical operations or power operations can be simplified further, so multiplication and division first, left to right:
(2r(r+2) -9(r+2) - r^2 + 17r +30)/(r+2)
(2r^2 + 2r -9r+18 -r^2 +17r +30 )/(r+2)
(r^2 +10r +48)/(r+2)
The ninth term will be 71.
8 3/5 - (1 1/2* 3 1/5)
= 43/5 - 24/5
= 19/5
= 3 4/5
Final answer: 3 4/5~

Answer:
It CAN be 28.30
Answer shortest side would
Be 18.
64 -18 = 46
46 divided by 2 = 23.
So if two of the sides was the same 18 would be the smallest one of the sides could be
