Answer 2

Пошаговое объяснение:

1) при a = 20

20 - 18 = 2; 20 + 24 = 44.

2) при a = 38

38 - 18 = 20; 38 + 24 = 62.

3) при a = 42

42 - 18 = 24; 42 + 24 = 66.

4) при a = 56

56 - 18 = 38; 56 + 24 = 80

Answer 3

To find the values of the expressions a-18 and a+24 for different values of a, simply substitute each value of a into the expressions:

1. For a = 20: a - 18 = 20 - 18 = 2 a + 24 = 20 + 24 = 44

2. For a = 38: a - 18 = 38 - 18 = 20 a + 24 = 38 + 24 = 62

3. For a = 42: a - 18 = 42 - 18 = 24 a + 24 = 42 + 24 = 66

4. For a = 56: a - 18 = 56 - 18 = 38 a + 24 = 56 + 24 = 80

So, the values of the expressions for each value of a are:

For a = 20: a - 18 = 2 and a + 24 = 44 For a = 38: a - 18 = 20 and a + 24 = 62 For a = 42: a - 18 = 24 and a + 24 = 66 For a = 56: a - 18 = 38 and a + 24 = 80
