Answer 1

Answer:

a. 1/6

b. 21

Step-by-step explanation:

a. (-2/-1)+(-1/3)+(3/-2)

2-1/3-3/2

1/2-1/3

1/6

b. 4+1+9-2+3+6

21

Answer 2

Step-by-step explanation:

a) x/y+y/z+z/x

Since x= -2, y= -1, z=3

Therefore,

-2/-1 -1/3 -3/2

2 -1/3 -3/2

= 1/6

b) x²+y²+z²-xy-yz-zx

Put values of x,y,z

(-2)²+(-1)²+(3)²-(-2×-1)-(-1×3)-(3×-2)

4+1+9-2+3+6= 21

Hope it helped you bro...:)
