Step-by-step explanation:
what you do is the red line in the middle is the surface area and you add those together to get the answer
30% + 10% = 40% off
150 * 0.40 = $60 off
150 - 60 = $90
Solution: you pay $90
Answer with Step-by-step explanation:
We are given that


We have to find the extreme values of the function.



Therefore,




Substitute the values in g(x)
Then, we get





When
then,

When 
Then, 


Hence, maximum value of f(x,y,z) is 23 at (2,2,1) and minimum value of f(x,y,z) is -23 at (-2,-2 ,-1).
Step-by-step explanation:
4.04285.
