Answer:
56 yds
Step-by-step explanation:
Simply add up all the sides to find your perimeter:
12 + 12 + 18 + 14 = 56
If their are 3 friends sharing 1.5 pizza you simply divide 1.5/3 = 1/2
Each friend gets 1/2 of the pizza
-6+4=-2
-100+45=-55
because you can't add two positive numbers together and get a negative so at least one of the numbers added has to be negative
