It’s 6 with a remainder of 4. So what we’re doing here is dividing 32 by 5. It’s pretty simple. Hope this helps!
N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n
Subtract 500 from each side
14850=10n
Divide by 10
n=1,485 books are printed
a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².
b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).
I hope this helps!
You can factor out the two, so you get 2(x^2-9). You can simplify it more because it is a difference of squares, so it should be 2(x-3)(x+3)
