Answer:
3
Step-by-step explanation:
Lannister checks out 6 sets of book
Each set had the same number of books
She reads 7 books and has 11 more to go
Therefore the number of books in each set can be calculated as follows
= 11+7
= 18
18/6
= 3
Hence there are 3 books in each set
The answer is B) 0 miles. Because displacement is the shortest distance between starting point and ending point. Since, his starting point and ending point is the same, hence, his displacement is 0 miles.
Answer:
5/9 or 0.5

i hope this helps :)
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5
Answer:
x = -3.5 or -1
Step-by-step explanation:
Add 7 and factor.
2x^2 +9x +7 = 0
(2x +7)(x +1) = 0
x = -3.5 or x = -1 . . . . . values that make the factors zero

<em>Comment on factoring</em>
Factoring ax^2 +bx +c = 0 requires you find factors of ac that have a sum of b. Here, you're looking for factors of 2·7 = 14 that have a sum of 9. If you're observant, you realize that 2+7=9, so 2 and 7 are the factors you want.
Now, you can write the factored form as ...
(ax +p)(ax +q)/a = 0 . . . . where p and q are the factors of ac we just found
The divisor "a" is used to simplify one or both of the factors. Here, we have ...
(2x +2)(2x +7)/2 = 0
(x +1)(2x +7) = 0 . . . . . . we removed a factor of 2 from the first binomial
