Answer 2

To evaluate the expression -9(0,3х - 8) + 4(18х - 2) when x = -0.2, we substitute the value of x into the expression and simplify the calculations.

Let's start with the first term: -9(0.3x - 8).

When x = -0.2: -9(0.3 * (-0.2) - 8) -9(-0.06 - 8) -9(-8.06)

Next, let's simplify the second term: 4(18x - 2).

When x = -0.2: 4(18 * (-0.2) - 2) 4(-3.6 - 2) 4(-5.6)

Now we can combine the two terms:

-9(-8.06) + 4(-5.6)

Multiply the numbers:

72.54 + (-22.4)

Combine the terms:

72.54 - 22.4

Finally, subtract:

50.14

Therefore, when x = -0.2, the expression -9(0.3x - 8) + 4(18x - 2) evaluates to 50.14.
