Answer 2

P = 2l + 2w
P = 2(l + w)
P = 2(6x^3y^2 - 1 + 3xy + 2)
P = 12x^3y^2 - 2 + 6xy + 4
P = 12x^3y^2 + 6xy + 2
P = 2(x^3y^2 + 3xy + 1)

Answer 3

P=2 ( l+ w )
= 2 [ (6x^3 y^2 - 1 ) + (3xy+2)]
= 2 ( 6x^3 y^2 + 3xy + 1)

Answer 4

There's nothing to simplify or calculate !

Answer 5

I hate when I still make a mistake regardless of posting solution first.

Answer 6

P = 2l + 2w
P = 2(l + w)
P = 2(6x^3y^2 - 1 + 3xy + 2)
P = 12x^3y^2 - 2 + 6xy + 4
P = 12x^3y^2 + 6xy + 2
P = 2(6x^3y^2 + 3xy + 1)
