penny has 25 dimes in a jar. she decided to arrange her dimes into 3 piles, putting an odd number of dimes in each pile. how many ways could she do this.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Idon’t know actually is more difficult
