We have been given a polynomial and we are asked to factor our polynomial by double grouping.
First of all we will group terms with common factors. We can see that 
and 2x have a common factor x. Common factor of -3x and -6 is -3.
Now we will factor out Greatest Common Factor from each group.
After factoring out GCF from each group we got (x+2) as our common binomial. Now we will write our polynomial as a product of two binomials as:
Therefore, our polynomial as a product of two binomials will be .
Answer:
of
Step-by-step explanation:
The first one is $4 per bag, as given
For the he second one, you divide $15 by 4, you got $3,75 per bag
Therefore, the second one has the better unit price
13.00 I think I don’t know if that correct but that’s what I got
Form of direct variation looks like y = kx, where k is any constant number (2, 3/4, 1/3, etc)
So here you have xy = 5.
Divide both sides by x, and you have y = 5/x.
So it is not direct variable, it is inverse variation.
