Answer 2

Let's break down and calculate each part of the expression step by step:

1. (-4) ^ 2 means (-4) raised to the power of 2, which is 16.
2. 3 / (-7) means 3 divided by -7, which is approximately -0.42857 (rounded to five decimal places).
3. (-1.5) * 9 means -1.5 multiplied by 9, which is -13.5.

Now, let's put it all together:

(-4) ^ 2 + 20 = 16 + 20 = 36 3 / (-7) + (-1.5) * 9 = -0.42857 + (-13.5) = -13.92857 (rounded to five decimal places)

So, the final result is:

36 + (-13.92857) = 22.07143 (rounded to five decimal places)
