Answer 2

To find out if the expression (39 * 737 + 39 * 281 - 39 * 296) is divisible by 13, we'll first calculate the value of the expression and then check if the result is divisible by 13.

Let's calculate the expression step by step:

1. 39 * 737 = 28743
2. 39 * 281 = 10959
3. 39 * 296 = 11544

Now, let's substitute these values back into the expression:

(28743 + 10959 - 11544)

Performing the addition and subtraction:

28743 + 10959 = 39702 39702 - 11544 = 28158

So, the simplified expression is 28158.

Now, let's check if 28158 is divisible by 13:

28158 ÷ 13 = 2166 with a remainder of 0.

Since the remainder is 0, it means that the expression (39 * 737 + 39 * 281 - 39 * 296) is divisible by 13, and the result of the division is 2166.
