Astring of holiday lights at a store have three colors that flash at different times. red lights flash every fifth second. blue lights flash every third second. green lights flash every four seconds. the store owner turns on the lights. after how many seconds will all three lights flash at the same time for the first time?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
