Answer:
60
Step-by-step explanation:
because half of children is 50. 120÷50=60
Answer:
x² + (x + 2)² + (x + 4)² = 12,296
x² + x² + 4x + 4 + x² + 8x + 16 = 12,296
3x² + 12x + 20 = 12,296
3x² + 12x = 12,276
x² + 4x = 4,092
x² + 4x + 4 = 4,096
(x + 2)² = 4,096
x + 2 = 64
x = 62
The numbers are 62, 64, and 66.
(62 × 64 × 66) ÷ 8 = 32,736
