The order of operations is used to order numerical expressions
Answer:
15
Step-by-step explanation:
5 - 3[ 2 + (-5)] 2 - 8
Subtract 5 from 2 to get −3.
5 - 3 (-3) × 2 - 8
Multiply 3 and −3 to get −9.
5 - (-9 × 2) - 8
Multiply −9 and 2 to get −18.
5 - (-18) - 8
The opposite of −18 is 18.
5 + 18 - 8
Add 5 and 18 to get 23.
23 - 8
Subtract 8 from 23 to get 15.
15

It is 12 sense the perimeter is the outside of the square you have to add the 2 numbers by themselves because they are the same measurement and 5+5=10 1+1=2 10+2=12
The first is not a polynomial as one term is dividing.
