Plsss help?! I think it might be 30 but I’m not sure‍♀️

p = 40.9

Step-by-step explanation:

perimeter can be found by adding up all the outside lengths of a figure.

in this case perimeter can be found like this:

p= 8 + 10+ 10 + 4 + 8.9

p = 40.9

(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

no he doesnt because "-16' is negatiive
