Answer 2

It looks like you're performing some mathematical operations with tuples. Let's break down the expression step by step:

(28, 47 - 45) • (-9, 38 + 9, 37)

First, let's simplify the tuples: (28, 2) • (-9, 47)

Now, let's perform the dot product (also known as the scalar product or inner product) of these two tuples. The dot product is calculated by multiplying the corresponding elements of the tuples and then summing up the results:

(28 * -9) + (2 * 47) = -252 + 94 = -158

So, the result of the expression is -158.
