Answer:
hi, 
So the answer is 420
Step-by-step explanation:
- You solve surface area by multiplying the length  and width 
- What I did first was do 14×6 which is 84
- Then I did 84 ×5 which is 420
I hope this help. Have a wonderful day,

Answer: ( -7 , -3 )
Step by step: 
The point: ( X , Y ) 
Left 2 units = change X by -2 
So, -5 subtract by 2 equals -7 
Down 3 units = change Y by -3 
So, 0 subtract by 3 equals -3 
Now, X = -7 and Y = -3, so the answer is ( -7 , -3 ) 
Hope this helps! Please tell me if I did anything wrong, thank you!

The dP/dt of the adiabatic expansion is -42/11 kPa/min
<h3>How to calculate dP/dt in an adiabatic expansion?</h3>
An adiabatic process is a process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression
Given b=1.5, P=7 kPa, V=110 cm³, and dV/dt=40 cm³/min
PVᵇ = C
Taking logs of both sides gives:
ln P + b ln V = ln C
Taking partial derivatives gives:

Substitutituting the values b, P, V and dV/dt into the derivative above:
1/7 x dP/dt +  1.5/110 x 40 = 0
1/7 x dP/dt +  6/11 = 0
1/7 x dP/dt = - 6/11
dP/dt = - 6/11 x 7
dP/dt = -42/11 kPa/min
Therefore, the value of  dP/dt is -42/11 kPa/min
