Answer 2

Explicación paso a paso:

1. a= -4; b= -7; c=8

a+b+c

(-4)+(-7)+(8) = -3

b+c

(-7)+(8) = 1

a+c

(-4)+(8) = 4

a+b

(-4)+(-7)=-11

2. a=5; b=-2; c=4

a+b+c

(5)+(-2)+(4) = 7

b+c

(-7)+(4) = -3

a+c

(5)+(4) = 9

a+b

(5)+(-2)=-10

3. a=-8; b=-3; c=9

a+b+c

(-8)+(-3)+(9) = -2

b+c

(-3)+(9) = 6

a+c

(-8)+(9) = 1

a+b

(-8)+(-3)= -11

4. a=6; b=-9; c=12

a+b+c

(6)+(-9)+(12) = 9

b+c

(-9)+(12) = 3

a+c

(6)+(12) = 18

a+b

(6)+(-9)= -3
