Answer:

$2.35 for one video

Step-by-step explanation:

You set up two equations:

$7.50= p + 2v

$12.20= p + 4v

You then set both equal to p

p=-4v+12.20 and p=-2v+7.50

So you can set them equal to each other and solve for v (the cost of one video)

v= $2.35

How do you factor: x^2-4x+2xy-8y?
hoa [83]

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

(x^{2}−4x)+2xy−8y

Factor out the greatest common factor (GCF) from each group.

x(x−4)+2y(x−4)

Factor the polynomial by factoring out the greatest common factor,  x−4.

(x−4)(x+2y)

I believe this is correct. Good luck.
