Answer:
24
P: parentheses (12 - 8) = 4
E: exponents (3^2) = 9
M: multiplication (12-8)/2 * 4 = 8
D: division (12-8)/2 = 2
A: addition (7 + 9 + 8) = 24
S: subtraction (blank)
Following the order of operations, our final answer is: 24
To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157
X= 23
Hope this helped :)
By the chain rule,
![\dfrac{\partial w}{\partial u}=\dfrac{\partial w}{\partial x}\cdot\dfrac{\partial x}{\partial u}+\dfrac{\partial w}{\partial y}\cdot\dfrac{\partial y}{\partial u}+\dfrac{\partial w}{\partial z}\cdot\dfrac{\partial z}{\partial u}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpartial%20w%7D%7B%5Cpartial%20u%7D%3D%5Cdfrac%7B%5Cpartial%20w%7D%7B%5Cpartial%20x%7D%5Ccdot%5Cdfrac%7B%5Cpartial%20x%7D%7B%5Cpartial%20u%7D%2B%5Cdfrac%7B%5Cpartial%20w%7D%7B%5Cpartial%20y%7D%5Ccdot%5Cdfrac%7B%5Cpartial%20y%7D%7B%5Cpartial%20u%7D%2B%5Cdfrac%7B%5Cpartial%20w%7D%7B%5Cpartial%20z%7D%5Ccdot%5Cdfrac%7B%5Cpartial%20z%7D%7B%5Cpartial%20u%7D)
![\dfrac{\partial w}{\partial u}=2xv+2y\cos v+2z\sin v](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpartial%20w%7D%7B%5Cpartial%20u%7D%3D2xv%2B2y%5Ccos%20v%2B2z%5Csin%20v)
We also have
![x(9,0)=0](https://tex.z-dn.net/?f=x%289%2C0%29%3D0)
,
![y(9,0)=9](https://tex.z-dn.net/?f=y%289%2C0%29%3D9)
, and
![z(9,0)=0](https://tex.z-dn.net/?f=z%289%2C0%29%3D0)
, so at this point we get
