Answer:
AB = 25 units
Step-by-step explanation:
In right triangle ACB,
Therefore, by geometric mean property:
AB = AD + DB
AB = 20 + 5
AB = 25 units

Answer:
Top is 18, Bottom goes 6 for 12, then 7 for 14, then 10 for 20
Step-by-step explanation:
2 guests = 1 table
Considering the spaces in the coefficients, I'm guessing the plane has equation
Let be the vertex of the box that lies in this plane. The box has volume
and we want to maximize this subject to the plane equation. Using the method of Lagrange multipliers, the Lagrangian is
with partial derivatives (set equal to 0)
We have
(we ignore and because those values correspond to a degenerate box with zero volume)
So we get a maximum volume of .
