Step-by-step explanation:
- 4 & 5 are roots
Therefore, (x + 4) & (x - 5) are factors.
Required quadratic equation is given as:
Answer: C - 15.81
Step-by-step explanation:
pythagorean theorum: a^2 + b^2 = c^2
13^2 + 9^2 = c^2
169 + 81 = c^2
c^2 = 250
root both sides
c = 15.81
Answers are y = 2 , y = 2.5
