Question

ME AJUDEM Sejam X = 20,Y = -15,Z= -120,W = 0, calcule

1) X-Y=
2) Y-X=
3) Z-Y+W=
4) (Y+W) + (X+Z)=
5) (Y+W) - (X+Z)
6) X.W + Y - Z=
7) W.(X-Y) - Z=
8) 3.(X + Y) - 2.Z=​

Answer 1

Resposta:

1)20-(-15)=35

2)(-15)-20=-35

3)(-120)-(-15)+0=-105

4)((-15)+0)+(20+(-120)=(-15)+(100)=85

5)((-15)+0)-(20+(-120)=(-15)-100=-115

6)20•0+(-15)-(-120)=0+105=105

7)0(20-(-15))-(-120)=0(35)+120=120

8)3•(20+(-15))-2•(-120)=15-(-240)=255
