![[n][n+8]=0](https://tex.z-dn.net/?f=%5Bn%5D%5Bn%2B8%5D%3D0)
if either or both of
![[n]](https://tex.z-dn.net/?f=%5Bn%5D)
and
![[n+8]](https://tex.z-dn.net/?f=%5Bn%2B8%5D)
are 0, i.e. if one or both of

and

are even. But both will be even if

is even, and odd otherwise, so any even

will be a solution, e.g.

.
Answer:
QM = 21
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, then
QM = PQ = 21
No because root(3)(x+8+1) is equal to x^3 -9 and (x-1)^3+8 is equal to root (3)(√x−8−1)
AB is similar to YZ
AC is similar to YX
CB is similar to XZ
you put the triangles next to each other. since they are the same shape. same kind of triangle. one is just bigger than the other.
