Answer 2

Answer:

3 ( 4)(-2) + 4 ( - 2) + 5

3 ( 4)(-2) + 4 ( - 2) + 5-24 + (- 8) + 5

3 ( 4)(-2) + 4 ( - 2) + 5-24 + (- 8) + 5-24 - 8 + 5

3 ( 4)(-2) + 4 ( - 2) + 5-24 + (- 8) + 5-24 - 8 + 5 - 32 + 5

3 ( 4)(-2) + 4 ( - 2) + 5-24 + (- 8) + 5-24 - 8 + 5 - 32 + 5= -27

3 ( 4)(-2) + 4 ( - 2) + 5-24 + (- 8) + 5-24 - 8 + 5 - 32 + 5= -27ans = -27
