Answer 3

It seems like there might be a formatting issue in the expression you provided. It's not clear how the components are meant to be grouped. Based on the context, it looks like you want to evaluate the expression (7x + 1) * 3 + 1, 2, but the comma and decimal point are causing confusion.

If you want to evaluate (7x + 1) * 3 + 1, 2 for a given value of x, you would first simplify the expression as follows:

(7x + 1) * 3 + 1, 2 = 21x + 3 + 1.2

Now, add the constants together:

21x + 3 + 1.2 = 21x + 4.2

So, the expression (7x + 1) * 3 + 1, 2 simplifies to 21x + 4.2. If you have a specific value of x, you can substitute it into this expression to find the result.
