part 1. So you would go and take it like this: there are 783 in 3 candy bars total you would take 783/3 candy bars and get the answer of 261 calories per a candy bar.part2. so you would go and take the 3 candy bars and pretty much divide them by the 792 from which gives you the answer of 264 per candy bar let me know if that helped thanks...;)
First find common factor for parameters. I mean to find common factor number 9,15,12 first, write the divisors: Divisors of 9: 1,3,9 divisors of 12: 1,2,3,4,6,12 divisors of 15: 1,2,3,5,15 so see, that GCF of 9,12,15 is 3.
Now, count GCF of x^2, x^4, x^6 GCF 2,4,6 is 2, so the result is x^2 and know finally GCF these terms is
