-2n(5 + n - 8 - 3n) = -2n(-3 - 2n) = 6n + 4n²
n = 3, subtitute
6 · 3 + 4 · 3² = 18 + 4 · 9 = 18 + 36 = 54

Answer:
The answer is 16.5 meters in 10 seconds
Step-by-step explanation:
First you divide 99 by 60 seconds
When you get 1.65 you multiply it by 10 second.
When you multiply 1.65 by 10 second you get 16.5 meters in 10 seconds
It wouldn’t let me use numbers so.. one times 10 to the 14th power
