(y * 4) + (4 * y * 3) + (2 * y * 2) - (3 * y)
(-2 * 4) + (4 * (-2) * 3) + (2 * (-2) * 2) - (3 * (-2))
(-8) + (-24) + (-8) - (-6)
-40 - (-6)
-34
Answer:
P+4=28, meaning that the original perimeter was 24
Step-by-step explanation:
Let's call the perimeter P.
Converting the words into an equation, you get:
P+4=28
Now, you can subtract 4 from both sides:
P+4-4=28-4
P=24
