I think its irrational bc if you put it as the squareroot of 329, it results in neverending decimals.
18^2=324+5=329
The picture is off point so I can’t read the entire paper!! Sorry and GOOD LUCK
1/8
If you can make the bottom numbers (denominator) The same that you can use subtract the top numbers like normally
a) 32.25* 40 = 1290
b) 32.25 (1.5) *12 =580.50
c) 1290+580.50=1870.50
