Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.
Answer:
x = 1
Step-by-step explanation:
The reason the answer is one because, 1^2 = 1
and 1 - 1 = 0
None of the above because no multiples of 5 have negative numbers.moreover b,c,d contains a even number except a which is also a negative number
Answer:
Step-by-step explanation:
32a²b² = 2 * 2*2*2*2 * a² * b²
36a²c² = 2 * 2 * 3 * 3 * a² * c²
16ab³ = 2 * 2 * 2* 2 * a * b³
Greatest common factor = 2*2*a = 4a
32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
