642

Step-by-step explanation:12(3*7+5*7)

12(21+35)

12*56=642

Answer 2

I'm pretty sure that it's 672

Explanation:

Ok, so all you gotta do is replace x with 7. so then it would look like 12(3(7)+5(7)). then you multiply whats inside the parenthesis so that you get 12(21+35). then you add, 12(56). then you just multiply.
