Answer:
Step-by-step explanation:
Which statement in the trailer is the hook?
A) Harry Potter seems at first glance normal, a boy living an unusual life with his dull and rather mean Dursley relatives.
B) However, on Harry’s eleventh birthday, he learns from a mysterious stranger, Rubeus Hagrid, that he is actually a famous wizard.
C) Forbidden by his uncle from seeking out his magical destiny, letters rain down inviting Harry to attend the magic school of Hogwarts.
D) What follows is an adventure story of intrigue, discoveries, and sacrifice.
In order of events:
A, C, B, D
A is where the story begins so it would be the best chose. It should catch you and make you want to know more. Also, the hook is usually the first sentence.
= 16 + 49 - 3(11) - 4(10)
= 16 + 49 - 33 - 40
= -8
recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.

So,
Since you can only take two one-credit courses every six months, you can earn 2 credits every six months, and 4 credits in one year. Multiplying that by 3, you get 12 credits in 3 years.
It will take 3 years to get the degree.
If that number is x:
120 = 1.60x
x = 120/1.60=75
