• It should be 2b. Don't forget to factor out the coefficients completely if that's your method. 28 = 2*2*7 and 30 = 5*3*2

• This comes down to a system of equations. y = -17.5 x = 255 3(-17.5) + 255 = 202.5 -3(-17.5) +150 = 202.5 Angle 1 = 202.5 Angle 3 = 202.5 They should and are equal because of vertical angles. There...

• Since you're multiplying them, you have to add the exponents (the images don't work by the way). We get each fraction into equivalent forms with common denominators: (3/4) = (9/12) and (1/3) = (4/1...

• First of all, e.g. means "for example", implying that it is an example not necessarily applicable to your question. If you mean the y-intercept is at (0,20), then you can just state the coordinate....

• According to https://blog.prepscholar.com/whats-the-difference-between-ap-physics-1-2-and-c, you probably only need math through Algebra II to understand what Khan Academy offers. I don't think KA ...

• This probably isn't the best place to ask a question. Your best bet would most likely be the combinatorics section of precalculus. You could probably go into a video's question section and you'll h...

• I think to make it different from the first time you learned the subject is to make acceleration much faster than the first time you completed it. It would make it so you don't have to spend too mu...

• Thanks for responding. For the US history section, the practice: "https://www.khanacademy.org/humanities/us-history/precontact-and-early-colonial-era/old-and-new-worlds-collide/e/old-and-new-worlds...
