Answer:
81 books
Step-by-step explanation:
If you divide 731 into 9 you'll get 81.2
so that means you have 2 books left over that wont be on the shelf
so you'll have to round to 81
Relationship B is represented by B. So C and D are both correct.
Well, if it descends 9 meters every minute, you would multiply 9 by the number of minutes in question. Since you want to know its location after 5 minutes, you would multiply 9 by 5.
9 x 5 = 45 so 45 meters after 5 minutes
Hope this helps :)

Answer:
49x² + 42x + 9
Step-by-step explanation:
Given
(7x + 3)²
= (7x + 3)(7x + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis
= 49x² + 21x + 21x + 9 ← collect like terms
= 49x² + 42x + 9
