Answer 2

It seems like you've provided a series of mathematical expressions. Let's break them down one by one:

B) (17+43) * 8: To evaluate this expression, you first need to calculate the sum inside the parentheses, which is 17 + 43 = 60. Then, you multiply the result by 8: 60 * 8 = 480.

e) 7 * (x + 9): In this expression, you have a variable, x, and a constant, 9. To evaluate it, you multiply 7 by the sum of x and 9.

и) a * (x + y): This expression involves two variables, a, x, and y. To evaluate it, you multiply the variable a by the sum of x and y.

Please note that without specific values assigned to the variables (x, y, and a), we can't provide a numerical result. However, I have explained how to evaluate these expressions given the variables present. If you provide specific values for the variables, I can help you calculate the results.
