Ответ:
1) -1+3·0= -1
2) 2-(-1)·(-3)= 2+1·(-3) = -1
3) (1+(-3))·2 = (1-3)·2 = -4
4)(3-1,2)·2= 3,6
5)(4-2)+(3-(-1)) = 2+(3+1) = 6
6) (0-(-4)) - (-2-3) = (0+4) -(-5) =4+5=9
7) 0,5-(1/2-(-1,2)) = 0,5 - (0,5+1,2) = -1,2
8) 5,2-(1,3-2,8)-2,8 = 3,9
Объяснение:
1)-1
-1+3*0=0
3*0=0
-1+0=-1
a) (p4q2-r3)(p4q2+r3)
б) (13-m+3)(13+m-3)=(16-m)(10+m)
в) (x3y2-x3+y2)(x3y2+x3-y2)=2y2*2x3
а) 12y+10-24y+16=0
12y=26
y=2*1/6
<u>y=3x^2-6x+1</u>
