372.
1→ a ;
2→(a- a*15/100) =0,85a.
3 →a + 85a  - 40 .

(1→) +(2→)+(3→) =a+(0,85a)+(a+0,85a -40) =3,7a -40 .
-------
373 .
б)   = -x² -x +4 -3x -4 +x² -1 = - 4x -1.
---
г) = 12ab -a² -11ab -a² +ab -6,2a² = -8,2a² +2ab .
-------
375.
б) = 4x +(2x-1) -(x-4)+1 =  4x +2x-1 -x+4+1 =5x +4.
-------
376.
б) A-B +C = (x²-2xy +y²) -(2x² -y²) +(x² -3xy) =
x²-2xy +y² -2x² +y² +x² -3xy = 2y²-5xy.
-------
377.
б) (a³ -b² -c) -(3a³ -2b²+c)+(2a³ -b²+2c) и 0.
(a³ -b² -c) -(3a³ -2b²+c)+(2a³ -b²+2c)=a³ - b² - c - 3a³ +2b²-c+2a³ -b²+2c =0 .
