Ella’s geometry teacher asked each student to devise a problem and write out its solution. Here is Ella’s work:

Answer:
Ella’s procedure and conclusion are incorrect.
Step-by-step explanation:
The sum of the squares of the short sides can be compared to the square of the long side to see if the triangle is acute, right, or obtuse. The appropriate conclusions are ...
- a² +b² > c² -- acute triangle
- a² +b² = c² -- right triangle
- a² +b² < c² -- obtuse triangle
For Ella's side lengths, the appropriate "work" is ...
10² +11² ?? 15²
100 +121 < 225
The triangle is obtuse.
__
Ella used an incorrect comparison and came to the wrong conclusion. Both her procedure and conclusion are incorrect.

Answer:
Where (a) is the side length of the hypercube
Step-by-step explanation:
A dimension can be simply defined as a direction in which matter can move it.
We live in a 3-dimensional world, matter can move in three basic directions. The formula for finding the volume of a cube is the following: (). In the second dimension, a flat world, the area for the volume of a square is as follows: (
). However, a hypercube is a paradox, as it exists in 4-dimensions, thus it cannot exist in our world. However, scientists propose "String theory" which requires that matter can move in more directs than the (3) we know of in our world. In essence, there can be more than 3 dimensions. A hypercube is the 4-dimensional version of a cube. If it follows the area pattern that a square-object follows in all preceding dimensions then the area of a hypercube is (
).
Bear in mind that the area patter for a square-object is generally the following:
Where (a) is the side length of the square-object
(n) is the dimension the object is in.
Please keep in mind, this answer was written in the June of 2021, as science keeps progressing and new discoveries are made, this theory can be disproven. Therefore, this answer might be considered correct now, but it can be proven incorrect in the future.
