![[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:
System of Equations
Step-by-step explanation:
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.
10=5×2 or 5×2=10 or 2×5=10 or 10=2×5
they're all the same thig but i'd probably go with 5×2=10 :)
Solution:
we have been asked to find the product of (x+y+3)(x+y-4).
we will multiply term by term as below
Hence the the product of (x+y+3)(x+y-4) is 
The answer is 81
A number squared means you multiply by itself 9*9=81
