<span>The Pythagorean theorem can be used to find a missing side length of a </span>right triangle
Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn
Pull out numbers and letters in groups of 2
2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5
Multiply the numbers and letters on the outside of the radical
4n x sqrt 5 is the final answer.
Answer: 19/25
Step-by-step explanation:
There are 25 markers in total and 6 of them are green. The odds of a student not getting a green marker would be the number of markers that aren’t green out of 25
25 - 6 = 19
19/25
