Is that the full question? I simplified it to 2x^2 -5x +18 when you plug x+3 in for the variable (x) in the expression. I’m honestly not sure when to go from there. Hope that helps with something. Sorry I couldn’t do more
The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.
The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock
12:30 p.m. = 12 hours 30 minutes = 12.50
5: 00 p.m. = 17 hours 00 minutes = 17.00
Difference between them:
= 17.00 - 12.50
= 4.5 hours
4.5 < 5
Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.
