A mixed number has a part that is whole and a part that is a friction.
For example:
3 1/2 and 3 2/3
3 1/2 * 3 1/4 = 7/2 * 13/4 = 91/8 = 11 3/8
9 < 11 3/8 < 12
2x=100%
2x-25% solve for x = 12.5%
Brett cannot spend more than $30, so the cost of the books and the shipping charge have to be less or equal to $30, we can express this as in an inequality, like this:
Where n is the number of books purchased, since each book costs $4, 4 times n equals the total cost of the books and 2 is the shipping charge. We can solve for n in the inequality like this:
Then, brett can afford no more than 7 books.
Answer:
B
Step-by-step explanation:
it's B because a polynomial it's like
so the only one is B
(x^3-4x^2)(4x-16)
x^2 (x-4) × 4 (x-4)
4x^2(x-4)
