Answer:
152 square inches
Step-by-step Explanation:
To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)
We should get 80+48+24 which add up to 152.

Answer: The difference is,
Step-by-step explanation:
Given expression is,
By distributive property,
Combine like terms( that have the same variables and powers ),
Which is the required result.
Hence, option third is correct.
Solution
Given data
According to Boyle's law, PV = K
The required general equation thus is
Substituting these values we find that the initial pressure is
The initial pressure to the nearest tenth, therefore, is 1.8 atm.
The final answer, therefore, is Option D
