Associative property just says you can multiply these together in any order. So this equation would work 18*(y*7)
1956/(3+1)=489 adult tickets cost for all adults
1965-489= 1467 cost of child tickets
1467/5.30=276.8
277 child tickets were sold.
Hello,
sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================
2m⁴ - 18n⁶
2(m⁴) - 2(9n⁶)
2(m⁴ - 9n⁶)
2(m⁴ - 3m²n³ + 3m²n³ - 9n⁶)
2[m²(m²) - m²(3n³) + 3n³(m²) - 3n³(3n³)]
2[m²(m² - 3n³) + 3n³(m² - 3n³)]
2(m² + 3n³)(m² - 3n³)
