In the Maths Olympiad of 2020 at Animal Planet, two representatives fr...
STUDENT 1:
Roots: 5,9.
Hence, x= 5..or x=9
or, x-5 = 0 or x - 9 = 0
or, (x - 5)(x - 9) = 0
or, x2 - 14x + 45 = 0
STUDENT 2:
Roots: 12,4
Hence, x= 12..or x=4
or, x - 12 = 0 or x - 4 = 0
or, (x - 12)(x - 4) = 0
or, x2 - 14x + 48 = 0

Team and two representatives from the elephant team were selected to participate. The participants were asked to solve a series of challenging math problems.
The first problem was as follows:
Problem 1: Find the value of x if 3x + 5 = 17.
Both teams quickly started working on the problem. The donkey team representative, named Jack, immediately wrote down the equation and began solving it step by step.
Jack's Solution:
3x + 5 = 17
Subtract 5 from both sides:
3x = 12
Divide both sides by 3:
x = 4
While Jack was busy solving the problem, the elephant team representative, named Emily, was also working on the problem. She had a different approach to solving it.
Emily's Solution:
3x + 5 = 17
Subtract 5 from both sides:
3x = 12
Divide both sides by 3:
x = 4
Both Jack and Emily arrived at the same solution, x = 4. They were both excited and proud of their teamwork and problem-solving skills.
The participants moved on to the next problem, eager to put their math skills to the test once again.

In the Maths Olympiad of 2020 at Animal Planet, two representatives fr...
Team and two representatives from the elephant team competed against each other. The donkey team representatives were named Alice and Bob, while the elephant team representatives were named Charlie and David.
The first round of the Olympiad was a multiple-choice test consisting of 20 questions. Each correct answer awarded 5 points, while each incorrect answer deducted 2 points. At the end of the round, the scores were as follows:
Alice: 75 points
Bob: 60 points
Charlie: 80 points
David: 70 points
In the second round, the participants had to solve 5 challenging problems. Each correct answer awarded 10 points. The scores after the second round were as follows:
Alice: 125 points
Bob: 100 points
Charlie: 110 points
David: 100 points
Finally, in the third round, the participants had to solve a single extremely difficult problem. The correct answer awarded 50 points. The scores after the third round were as follows:
Alice: 175 points
Bob: 150 points
Charlie: 160 points
David: 150 points
Thus, at the end of the Maths Olympiad of 2020 at Animal Planet, the rankings of the representatives were as follows:
1. Alice: 175 points
2. Charlie: 160 points (tied with David)
3. David: 160 points (tied with Charlie)
4. Bob: 150 points
