So that equation was definitely correct...
When you expand the equation in the bracket you'll find out that you'll get a^6 + 4a^4 + !6a^2 - 4a^4 - 16a^2 -64. then your final result will be a^6 - 64

Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.
I think it's 42 since 7x6=42
sin α = opposite leg/ hypotenuse
For ΔABC,
sin A = |BC|/|AB|
sin A = 12/37
Its d 729 because on 1 layer theres are 81 cubes and there are 9 layers so 81 times 9 equals 729
Hope this helps
