# p is defined as 2 p + 20 for any number p . what is p , if # ( # ( # p ) ) = - 4 ?
# p = 2 p + 20 - - - > # ( # p ) = 2 ( 2 p + 20 ) + 20 = 4 p + 60 and thus # ( 4 p + 60 ) = 2 ( 4 p + 60 ) + 20 = 8 p + 140 = - 4 - - - > 8 p = - 144 - - - > p = - 18 , d is the correct answer .
divide(add(add(add(multiply(multiply(20, const_2), 2), multiply(20, const_2)), 20), 4), multiply(4, const_2))
