Answer 3

To simplify the expression, let's calculate each term separately and then perform the additions:

1. First, we'll calculate 12.37 * (-2.1):

   12.37 * (-2.1) = -25.977

2. Next, we'll calculate (-3.37) * (-2.1):

   (-3.37) * (-2.1) = 7.077

3. Finally, we'll add the two results together:

   -25.977 + 7.077 = -18.9

Therefore, the value of the expression 12.37 * (-2.1) + (-3.37) * (-2.1) is -18.9.
