Answer:
80 units squared
Step-by-step explanation:
well first you get the area of the big rectangle, 8x12=96
then you need to get the area of the light sqaure, because there is the same amount of ticks 3 times, the equal lengths are 12/3= 4 units each so the dimensions of the sqaure are 4 by 4 4x4=16 then you do 96-16= 80 units squared.
The unit measure that is appropriate would be Cubic meters
I think it is c. They are all prime numbers
I would say -13 because y = - 10 - 3 would mean that what ever -10 minus 3 equals is what y equals and -10 - 3 is -13
A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.
Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.
