Hmm, this one's a real brain-teaser. I'm gonna have to go with B, 1 + 3x. It's like a puzzle, you just gotta find the right pieces and put them together. Hey, at least it's not a word problem, right? I hate those.
The answer is clearly A, 1 + 2x. Anything else is just plain wrong. It's like trying to simplify x^2 - x^2 - it's just 0, end of story. Come on, people, let's keep it simple!
I'm pretty sure the answer is C, 1 + 5x. Simplifying those expressions is like a dance, you just gotta go with the flow, you know? Hey, at least it's not calculus, right?
