Answer:
x = 8 or x = -1 is the answer
Step-by-step explanation:
3x² - 21x -24
divide with 3
x² - 7x - 8
Factorizing,
x² + x - 8x - 8
x(x + 1) -8 (x + 1)
(x - 8) (x + 1)
x = 8,-1
Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=8
leg₂=15
hypotenuse=s
hypotenuse²=(8)²+(15)²
hypotenuse²=64+225
hypotenuse²=289
hypotenuse=√289
hypotenuse=17
Answer: s=17
