Determine whether wx←→− and yz←→ are parallel, perpendicular, or neither.

w(−2,−1),x(4,1),y(1,−4),z(5,−4)

Neither

Step-by-step explanation:

We have to determine whether WX and YZ are parallel, perpendicular or neither.

Coordinates are W(-2, -1) X(4, 1) Y(1, -4) and Z(5, -4)

Now we will find the slopes of WX and YZ.

Slope of WX = =  

                     =    =  

Slope of YZ =   = 0

Since there is no relation in slopes of WX and YZ. Therefore, answer will be Neither.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
