Answer 2

To find the values of the expressions a-18 and a+24 for different values of a, let's substitute the given values of a and calculate the results:

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 = -74 a + 24 = -56 + 24 = -32

So, the values of the expressions for different values of a are as follows:

• 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 = -74 and a + 24 = -32
