Answer 2

To solve these expressions, let's simplify them step by step:

1. -13.4 * 0.6 + (-2.3) * 3.8

First, multiply each pair of numbers: -13.4 * 0.6 = -8.04 (-2.3) * 3.8 = -8.74

Now, add the results together: -8.04 + (-8.74) = -16.78

Therefore, -13.4 * 0.6 + (-2.3) * 3.8 equals -16.78.

2. (28.47 - 45) * (9.38 + 9.07)

First, subtract 45 from 28.47: 28.47 - 45 = -16.53

Then, add 9.38 and 9.07: 9.38 + 9.07 = 18.45

Now, multiply the results together: -16.53 * 18.45 = -304.1385

Therefore, (28.47 - 45) * (9.38 + 9.07) equals -304.1385.
