The formula would be: X(X+1)=6162.
X^2+X = 6162.
X^2+X-6162 = 0; Factor this.
(X+79)(X-78)=0.
X+79=0 or X=-79; impossible.
X-78=0; X=78; first page.
Second page X+1=79.
Therefore page numbers are 78 & 79.
Check: 78*79=6162.
The two page numbers are 64 and 65. 64 x 65 = 4160.
If one of the pages is numbered p, the other is p+1. So p*(p+1) = 420 That is, p2 + p - 420 = 0 which factorises as (p - 20)*(p + 21) = 0 That implies that p = 20 or p = -21. Assuming that pages do not have negative numbers, p = 20 and then the other page is p+1 = 21.
52 and 53
The solution is: Let X = left page and X+1 = right page. X + (X+1) = 89. Solve for X; X = 44 which is left page and right page is X+1 = 45.
well the answer will be 2 consecuitive numbers, so 127 divided by 2 = 60.5 so you have 60.5 and 60.5, round one down to 60 and round the other to 61 so the pages are 60 and 61! does that make sence, i think so!
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.
The two page numbers are 64 and 65. 64 x 65 = 4160.
Let the two facing pages be represented by x and (x+1). Since the product of the page numbers is 1056, we have the equation x(x+1) = 1056. This simplifies to x^2 + x - 1056 = 0. By solving this quadratic equation, we find the page numbers to be 32 and 33.
They are 44 and 45.
40 & 41
They are pages 42 and 43 because the product of both numbers is 1806
122 and 123How?|vif the page is double sided then it has two numbers that are added... divide 245 by 2 and you get 122.5 so one page is pg. 122 and the other is pg. 123
If one of the pages is numbered p, the other is p+1. So p*(p+1) = 420 That is, p2 + p - 420 = 0 which factorises as (p - 20)*(p + 21) = 0 That implies that p = 20 or p = -21. Assuming that pages do not have negative numbers, p = 20 and then the other page is p+1 = 21.
52 and 53
Facing the Future has 160 pages.
Facing Mount Kenya has 339 pages.
42 and 43 because 42*43 = 1806
