Answer:
-7
Step-by-step explanation:
Because there is no multiplication, it is just the x^2 terms. There is a -(-2x^2) and a -9x^2, so it is 2x^2 and -9x^2 or -7x^2, so the coefficient is -7.
Find the circumference of the pool. I guess you guys here mostly replace pi with 3.14 so that's what we will do. C = 3.14(16) and that gives us a circumference of 50.24 ft.
Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
