Answer 1

Ответ:

4+17=21

Пошаговое объяснение:

2(2)-(3+(-20))=?

4-(-17)=?

4+17=21

Answer 2

To find the value of the expression 2|x| - |3 + y| when x = 2 and y = -20, you simply need to substitute the given values and perform the calculations.

Step 1: Substitute the values of x and y into the expression:

2|x| - |3 + y| = 2|2| - |3 + (-20)|

Step 2: Perform the absolute value calculations:

2|2| = 2 * 2 = 4 |3 + (-20)| = |-17| = 17

Step 3: Calculate the final result:

2|2| - |3 + (-20)| = 4 - 17 = -13

So, when x = 2 and y = -20, the value of the expression is -13.
