A rectangle has congruent diagonals because if you draw them out, the parallelogram has one diagonal that is long and one that is short
trapezoids dont necessarily have congruent diagonals
rectangles have to have congruent diagonals

Step-by-step explanation:
If the cost of the party supplies was $316. Then the amount of money spent by each of them is $158.
<h3>What is division?</h3>
Division means the separation of something into different parts, sharing of something among different people, places, etc.
Keri and Samantha are equally splitting the cost of party supplies for their mom's surprise birthday party.
The total cost of the party supplies was $316.
Then the money spent by each of them will be
![\rightarrow \dfrac{316}{2}\\\\\rightarrow 158](https://tex.z-dn.net/?f=%5Crightarrow%20%5Cdfrac%7B316%7D%7B2%7D%5C%5C%5C%5C%5Crightarrow%20158)

Answer:
Step-by-step explanation:
Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2
