Answer:

-1(3 - y)

Step-by-step explanation:

If you factor out a negative 1, you will get the opposite signs you already have, so -1(3 - y). To check, we can simply distribute again:

-3 + y

So our answer is 2nd Choice.

Answer:

A $x=4$

Step-by-step explanation:

Perimeter = the sum of all side lengths

Perimeter = $(x-3)+2x+6$

Perimeter = 15 (in this case)

so...

$(x-3)+2x+6=15$

And we're trying to solve for x.

Step 1. Subtract 6 to both sides

$(x-3)+2x=9$

Step 2. Add 3 to both sides

$x+2x=12$

Step 3. Combine like terms

$3x=12$

Step 4. Solve for x

$x=\frac{12}{3}$

$x=4$
