Add 8.1 to both sides to find x!
hope this helps :-)
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
Hope I helped :)
For 5 you would need 1,000 ml of water and 7 you need 1,400 ml
Do you need for both or just one?
270 because 120/24 = 5 5x54 = 270
