In this question , we have to find the postulate that is illustrated for the real numbers

The postulate is Additive inverse postulate which states that

Where a is the real number and -a is the opposite of a. It states that , if opposite of a number is added with the number, the result is 0 .
Answer:
B, 140
Step-by-step explanation:
Alright so if you know to do volume this should be a breeze!
First off what you want to do is find the volume of the outside prism.
V=whl=4·5·8=160
160
Then find the smaller prisms volume.
V=whl=1·5·4=20
20
Minus the smaller from the bigger
160-20=140
The answers B!
This can be done algebraically:
300*x=330 Where x is the multiplier
Therefore x=330/300=1.1
To find a percentage of a number you multiply by the percentage divided by 100.
So 330 is 110% of 300, which is an increase of 10%.
