'y' is NOT the number of chairs in each row and column. It's the TOTAL number of chairs, so it's the product of (chairs in each row) times (chairs in each column). The problem says that those numbers are equal. So we would expect the TOTAL to be a perfect square, and the number in each row and each column to be the square root of the total. Since the total is 81, the number in each row and column could be either +9 or -9 . Both answers are mathematically correct, but -9 doesn't make sense in the real world. So we know that +9 is the real answer.

The number of chairs in each row and column, given that the total number of chairs is 81, is 9 because 9 × 9 = 81 . This is found by taking the square root of the total number of chairs. Therefore, both rows and columns consist of 9 chairs each.

Jawaban:Kualitas sumber daya manusia (SDM) biasanya dinilai menggunakan kriteria yang dikembangkan oleh United Nations Development Programme (UNDP) melalui Indeks Pembangunan Manusia (IPM) atau Human Development Index (HDI).UNDP menilai kualitas SDM berdasarkan tiga indikator utama:Umur panjang dan hidup sehat → diukur melalui angka harapan hidup.Pengetahuan (pendidikan) → diukur melalui angka melek huruf, rata-rata lama sekolah, dan harapan lama sekolah.Standar hidup layak → diukur melalui pendapatan nasional bruto (PNB) per kapita. Jadi, kriteria penilaian kualitas SDM dikembangkan oleh UNDP melalui HDI/IPM.Penjelasan:karena kriteria UNDP melalui IPM/HDI memberikan ukuran yang komprehensif, objektif, dan diakui secara internasional untuk menilai kualitas SDM, mencakup kesehatan, pendidikan, dan ekonomi.
