Annie is selling 360 candies for 5 for one dollar. how much money would she get if she sold it all

As you are selling each candy in a packet of 5, you should First divide 360 by 5. This would give you how many let’s say packets you would sell. This would give you 72. Each once you sells at one dollar. Therefore if you sell a total of 72 packets you will do 72 multiplied by 1, which would give you a total of $72z

  ab = 2

Step-by-step explanation:

You know that ...

  (a +b)^2 = a^2 +2ab +b^2

Rearranging, we can solve for ab ...

  2ab = (a^2 +b^2) -(a +b)^2

  ab = ((a +b)^2 -(a^2 +b^2))/2 = (3^2 -5)/2

  ab = 2
