(n^4 - 1) = (n^2 - 1) (n^2 +1) = (n - 1) (n + 1) (n^2 + 1)
Answer:
A cube shaped box can hold 42.875 cubic ft if each side measures 3.5ft
Step-by-step explanation:
We have given a cube shaped box.
Each side of a cube measures 3.5ft
A cube shaped box can hold up-to its maximum volume capacity.
That means , we need to find the volume of cube.
volume of cube =
Here side = 3.5 ft
So, volume of cube =
Volume of cube = 42.875 cubic ft
The distance between points M and N according to the task content is; 9.8 meters.
<h3>What is the distance between points M and N?</h3>
From observation of the task content information; it can be deduced for a fact that the line segment MN which joins points M and N is parallel to the line JK. This follows from the fact that M and N are midpoints KL and JL respectively.
Hence, it follows that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality;
NM/19.6 = 7.4/(2×7.4)
NM = 19.6/2 = 9.8 meters.
This follows from congruence theorems in which case, the ratio of corresponding sides of congruent triangles are equal.

All you would do is divide for this problem so,
13.75 ÷ 5 = 2.75
So one pack would cost 2.75
