Step-by-step explanation:
Answer:Scientific Notation:9.8421*10^-4
Step-by-step explanation:
Number 9 is A number 10 is C and number 11 is B thank you for your time
Since p = x² - 7, you can substitute/plug in p for x² - 7
So:
(x² - 7)² - 4x² + 28 = 5
(p)² - 4x² + 28 = 5 You can factor out -4 from (-4x² + 28)
p² - 4(x² - 7) = 5 Plug in p
p² - 4p = 5 Subtract 5
p² - 4p - 5 = 0 Your answer is C
1. 12/5
2. 24/10
3. 48/20
4. 96/40
