Answer:
- 984 adults
- 281 teens
- 492 children
Step-by-step explanation:
Multiply the total by the corresponding percentage to find the number. We assume the percentages have been rounded, so some adjustment is needed in the result of the multiplication.
{adults, teens, children} = 1757 × {.56, .16, .28} = {983.92, 281.12, 491.96}
≈ {984, 281, 492}
The visitors included 984 adults, 281 teens, and 492 children.
Using long division, we have
The parenthesis are the result of what we multiply (a^n+8) by (we multiply it by the top expression - we start with a^2 then -1), and what's not is the result of adding the parenthesis to the expression about that.
Our final result is (a^n+8)*(a^2-1)-8a^2-14
