Answer: Reformatting the input :
Changes made to your input should not affect the solution:
(1): "y3" was replaced by "y^3". 1 more similar replacement(s).

Trying to factor as a Difference of Cubes
2.1 Factoring: 8x2y3-5
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 8 is the cube of 2
Check : 5 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Final result :
8x2y3 - 5

We are told that each person flips a coin 200 times. We know that a coin has two options when heads or tails fall, therefore, the results between Amir and Marvin are compared with the number of heads and the number of tails that each one obtained.
The theoretical probability says that out of 200 times a coin is flipped by having 50% heads or tails come out, 100 must be heads and 100 must be tails, theoretically obviously speaking.
Therefore with these values it would be the comparison.
Since the ground already has an elevation of 15 degrees, the ladder needs to
be set at 60 degrees to reach a height of 10 ft.
In order for a ladder to reach a height of 10 feet, the ladder needs to be
placed at 75 degrees angle to the ground. This is when the ground has no
angle of elevation or when it flat.
Now, if the ground has an angle of elevation of 15 degrees , the degrees in
angle the ladder needs to be set can be solved as follows:
<h3>Angles in degree: </h3>
Therefore, the ladder needs to set at an angle of 60 degrees if the
elevation of the ground is already 15 degree. The elevation of the ground
will complement the angle in degrees required for the ladder to reach 10
feet.
