Answer 3

To find the value of the expression (11a - 9b) - (11a + 9b), we can simplify the expression step by step:

Step 1: Distribute the negative sign across the second parentheses by changing the signs inside the parentheses: (11a - 9b) - 11a - 9b

Step 2: Combine like terms: 11a - 11a = 0a (any number multiplied by 0 is 0) -9b - 9b = -18b

So, the simplified expression is: 0a - 18b

Since any number multiplied by zero is zero, the value of the expression is simply 0 - 18b, which is equal to -18b.
