what is the slope of a line that is perpendicular to a line whose equation is 5y=10+2x



would it be -5/2 as in only the 5 is negative or the whole fraction is negative?

The slope of the line would be -5/2, and the whole fraction would be negative.  

Step-by-step explanation:

Technically just the 5 is negative because the new slope is going down 5, yet on paper its just safer to write the whole fraction as a negative.

(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

answer: huh
