expressions ?
STUDENT
Abigail
Bailey
Carlos
EXPRESSION
-(4h - 3s + 1)
-4h + 3s +1
-4h + 3s - 1
d. Abigail and Bailey
b. Bailey and Carlos
c. Carlos and Abigail
d. They are all equivalent.​

The first expression and the third expression

Step-by-step 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
