Answer 2

Let's calculate the expression step by step:

1. Start with the subtraction inside the parentheses: 289 - b.
2. Multiply the result by 4: 4 * (289 - b).
3. Finally, subtract this result from 14,289: 14,289 - 4 * (289 - b).

Now, we can simplify the expression:

14,289 - 4 * (289 - b)

To calculate the expression, we need to subtract the result of 4 * (289 - b) from 14,289:

14,289 - 4 * (289 - b)

First, calculate the value inside the parentheses:

289 - b

Now, multiply it by 4:

4 * (289 - b)

Next, subtract this value from 14,289:

14,289 - 4 * (289 - b)

Now, you can calculate 4 * (289 - b):

4 * (289 - b) = 4 * 289 - 4 * b = 1156 - 4b

Now, subtract this from 14,289:

14,289 - (1156 - 4b)

To subtract, distribute the negative sign inside the parentheses:

14,289 - 1156 + 4b

Now, subtract 1156 from 14,289:

14,289 - 1156 = 13,133

So, the simplified expression is:

13,133 + 4b

The result is 13,133 + 4b, not 424,2000.
