Which expression has a value of -2? *<br> O 1-4+121<br> O 121 +1-41<br> O 141-121<br> O 1-21-1-41
irga5000 [103]

Answer:

None.

Step-by-step explanation:

1 - 4 + 121

= -3 + 121

= 118

121 + 1 - 41

= 122 - 41

= 81

141 - 121

= 20

1 - 21 - 1 - 41

= -20 - 1 - 41

= -21 - 41

= -62

None of the expressions have a value of -2.
