You need to specify the statement needed to use the equation. Thank you. I will then answer it if needed.
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
10% of 59 = 5.9
59 - 5.9 = 53.1
