Answer: 3(x+4)=x+18
Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.
Answer:
the g's contributing term for the overall uncertainty of P is ![dP_g = [\frac{dg}{g}]](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D)
Step-by-step explanation:
From the question we are told that
The pressure is 
The first step in determining the uncertainty of P in by obtaining the terms in the equation contributing to it uncertainty and to do that we take the Ln of both sides of the equation

=>
Then the next step is to differentiate both sides of the equation

=> 
We asked to obtain the contribution of the term g to the uncertainty of P
This can deduced from the above equation as
![dP_g = [\frac{dg}{g}] P](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D%20P)
