Step-by-step explanation:
Imagining living a life for five hundred years in the future, can have two perspectives considering the reality of today's society.
Let us suppose that we currently overcome all challenges related to preserving the environment, sustainable consumption, violence, and racial discrimination. Well, considering that point of view, a typical day five hundred years from now would be a lot of fun, I imagine that we would have great biodiversity preservation centers, people would be more cordial with others, everyone would have access to education and essential rights, and we would use more bicycles as a means of transport, because even if they had already managed to invent teleportation, the bicycle would still be a good option for the practice of physical exercises.

The area of a door is 3024 square inches. If the length of the door is 48 inches longer than the width of the door, what is the width of the door?
Answer:
The width of the door is 36 inches
Step-by-step explanation:
The given parameters are;
The given area of the door = 3024 in.²
The length of the door = 48 + The width of the door
Let W represent the width of the door
Therefore, we have;
The length of the door = 48 + W
The area of the door = The length of the door × The width of the door
∴ By substitution, the area of the door = 3024 = W × (48 + W)
3024 = W × (48 + W) = 48·W + W²
48·W + W² = 3024
∴ 48·W + W² - 3024 = 0
Rearranging, we get;
W² + 48·W - 3024 = 0
By trial and error, we have;
(W + 84)×(W - 36) = 0
Therefore, given that the width of the door is a natural number, we have;
The width of the door, W = 36 inches

423 divided by 2 is 216
432 is also divisible by three!!
432 divided by three is 141
The number 432 is divisible by 2 and 3 both as its unit digit is even and the sum of the digits is 9.
What is the divisibility rule?By the divisibility rule, we can determine whether numbers are divisible by some other numbers or not without dividing.
We know a number is divisible by 2 if its unit digit is even and a number is divisible by 3 if the sum of the digits is divisible by 3.
Given number is 432 unit digits even, therefore, it is divisible by 2,
and the sum of the digits is 9 so it is also divisible by 3.
