Question

Which of these expressions have negative values? Select all that apply.

A) 2 + 2(-3)(7)
B) 0 - 2(27 - 9) + 4
C) (14 = -2)(-6)
D) (4 - 10) - (8 = (-2))

Answer 1

The expressions that have negative values are A) 2 + 2(-3)(7), B) 0 - 2(27 - 9) + 4, and D) (4 - 10) - (8 = (-2)).

Step-by-step explanation:

The expressions that have negative values are:

1. A) 2 + 2(-3)(7)
   To calculate this expression, we first multiply -3 and 7 to get -21. Then, we multiply 2 and -21 to get -42. Finally, we add 2 and -42 to get -40. So, this expression has a negative value.
2. B) 0 - 2(27 - 9) + 4
   Inside the parentheses, we subtract 9 from 27 to get 18. Then, we multiply 2 and 18 to get 36. Finally, we subtract 36 from 0 and add 4 to get -32. So, this expression has a negative value.
3. D) (4 - 10) - (8 = (-2))
   Inside the parentheses, we subtract 10 from 4 to get -6. Then, we subtract -2 from 8 to get 6. Finally, we subtract 6 from -6 to get -12. So, this expression has a negative value.
