Answer:
9 bows
Step-by-step explanation:
Take the amount of ribbon and divide by the amount needed per bow
2 1/4 ÷ 1/4
Change the mixed number to an improper fraction
(2*4 +1)/4 ÷1/4
9/4 ÷1/4
Copy dot flip
9/4 * 4/1
9
9 bows
Answer:
They are similar however i don't see where the a is at. If you see G would go to S which means H would go to R. I think the answer is B
Step-by-step explanation:
The polynomial has three real roots (of which one counts twice). It's formula is
The roots of a polynomial are the points in which the polynomial inersects the x-axis. So, you might be tempted to say that there are two roots, and .
But now let's face the problem in an analytic way: if is a solution for the polynomial , then can be factored as where is some remainder.
So, since we are sure that and are solutions, we know that we can write our polynomial as
But since the polynomial is a cubic (i.e. degree 3), must be a polynomial of degree 1, i.e. for some
But then we would have
and so we would have a third solution , but we can see from the graph that the only solutions are and .
This means that is actually a copy of one of the two other factors, so that it doesn't add new solutions. So, we have two cases:
or
The answer lies in the shape of the polynomial: you can see that the graph is tangent to the x-axis in , whereas it crosses the x-axis at . This tells us that the double solution is , and thus the correct solution is
Answer:
Step-by-step explanation:
630 tree:
2x315
5x63
3x21
3x7
So its 2x5x3x3x7
Or, 2x5x3^2 x 7.
Hope this helps :D
