Evaluate the expression for a = 2 and b = 3. 3(a + 5) - 4b

Answer 1

To evaluate the expression for a = 2 and b = 3, we substitute the values of a and b into the expression:

3(a + 5) - 4b

Substituting a = 2 and b = 3:

3(2 + 5) - 4(3)

Simplifying inside the parentheses:

3(7) - 4(3)

Multiply:
21 - 12

Subtract:
9

Thus, when a = 2 and b = 3, the expression 3(a + 5) - 4b evaluates to 9.
