Answer:
Non fiction : Total number of books
= 14 : 42
= 1:3
Step-by-step explanation:
Total number of books = 42 books
Non fiction books = 14 books
The ratio of the number of non-fiction books to the total number of books is :
Non fiction : Total number of books
= 14 : 42
Further simplified
= 1:3
Answer: she scored 600 points
Step-by-step explanation:
-900+600
-300
The rational root theorem tells you all roots are of the form
±(factor of 2)/(factor of 3)
We know one of the roots is -1 and all roots are negative, so the remaining roots must be of the form
-(factor of 2)/(factor of 3)
which is to say, two of
-1/3, -2/3, -1, -2
Since the roots are distinct, they must be -2 and -1/3. Then the factorization of the given polynomial is
(x +1)(x +2)(3x +1)
which multiplies out to be
3x³ +10x² +9x +2
a = 10
b = 9
