It’s the first one because the parabola is open
Answer:
x^2 + 22x + 121
Explanation:
Answer: 26 years.
Step-by-step explanation:
Let x = current age of Louise (in years).
Then current age of James = x+6
Eight years from now, James's age = x+6+8= x+14
4 years ago, Louise's age = x-4
According to the question
x+14 = 4(x-4)
⇒ x+14 = 4x-16
⇒ 4x-x = 16+14
⇒ 3x = 30
⇒ x= 10 = current age of Louise (in years).
current age of James = 10+6 = 16 years
Sum of current ages = 16+10=26 years.
hence, the sum of the current ages is 26 years.
The larger the mass, the smaller speed as the kinetic energy is the same, and the more polar the molecule, the harder for it to escape from its pals, so the smaller its speed as it deviates more from ideal gas.
Therefore H2 is the answer
