Answer 1

The correct answer is C
Carols and Abigail

Answer 2

The first expression and the third expression

Explanation:

This is because if you simplify the first expression, you have to multiply

-(4h-3s+1)

And you have to make the +/- symbols opposite from the negative symbol on the left when you multiply

so you get..

-4h+3s-1, which is also the third one

So the first one and the third one are the same expressions
