Using Lagrange multipliers, we have the Lagrangian

with partial derivatives (set equal to 0)




Substituting the first three equations into the fourth allows us to solve for

:

For each possible value of

, we get two corresponding critical points at

.
At these points, respectively, we get a maximum value of

and a minimum value of

.
Answer:
52
Step-by-step explanation:
180 - 127 = 53
53 + 75 = 128
180 - 128 = 52
237.3f= 1b. Explanation: is 712/3(237.3) so 1b is 237.3f
