Answer 2

Given Information

According to the given information, we know that 1 < a < 7 and 3 < b < 4.

Evaluating Expressions

a) To evaluate the expression a + a + b, we can substitute the given values for a and b into the expression and calculate the result.

Since a is between 1 and 7, we can choose any value within that range. Let's choose a = 3.

Substituting a = 3 into the expression, we get: 3 + 3 + b

Since b is between 3 and 4, we can choose any value within that range. Let's choose b = 3.5.

Substituting b = 3.5 into the expression, we get: 3 + 3 + 3.5 = 9.5

Therefore, the value of a + a + b is 9.5.

b) To evaluate the expression ab, we can substitute the given values for a and b into the expression and calculate the result.

Using the same values as before (a = 3 and b = 3.5), we can substitute them into the expression: 3 * 3.5 = 10.5

Therefore, the value of ab is 10.5.

To summarize: a) The value of a + a + b is 9.5. b) The value of ab is 10.5.
