Answer:
10
Step-by-step explanation:
- and a - equal postive and 8 plus 2 is 10
Answer:
y = -8x + 80 This is the way I found the answer
Lagrangian:

where the function we want to minimize is actually

, but it's easy to see that

and

have critical points at the same vector

.
Derivatives of the Lagrangian set equal to zero:




Substituting the first three equations into the fourth gives


Solving for

, we get a single critical point at

, which in turn gives the least distance between the plane and (0, 2, 5) of

.
Answer:
3.6
Step-by-step explanation:
Using the area of rectangle formula L*W= A
we can plug in our known values
20*w=72
then we can divide 20 on both sides giving us 3.6 inches for width.
I would say he is incorrect because integers are both negative and positive
