Question

What does 2b+9 when b=3 like the hell

Answer 1

You plug 3 into B so 2(3) + 9 = 15

Answer 2

So let’s start from the beginning. 2 is by B, so that means we have to MULTIPLY 2 by whatever B equals. B equals to 3, so we have to multiply 2 by 3, which equals 6. Then, we add 6 and 9, which is 15. Your final answer is 15. Hope that helps!
