    so how can we figure out the number of hexagons from there?

    ok do you see how I'm getting 50 sticks for this next pattern?

    oops I made a typo on the first image attachment. I meant to say 15+15-2 = 28

    kinda. so if we had then three sets of the hexagon we would have: 28 x 3 = 84 since two sets has 6 sticks being subtracted, then in three sets would it be 12 sticks out?

    teacher said that it won't be exactly 95. she also said that there will like 15 hexagons total and one stick left over i think?

    but how did u get 15 regular hexagons? i see like 20 hexagons?

    I count 3+3 = 6 hexagons given to you in the problem there are four groups of this pattern repeated (in two different configurations). So 4*6 = 24 hexagons total

    yeah and you subtract off the portions where the hexagons are joined (to correct for double counting)

    6 hexagons per block * 4 blocks = 24 hexagons total

    i thought there were five hexagons. i found my mistake... but my teacher said fifteen... we are getting 24 here.

    that is strange why s/he said 15 when there are more hexagons possible
