79 x 1 39.5 x 2
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.
To find 2 percent of a number, multiply the number by 0.02. In this instance, 0.02 x 79 = 1.58. Therefore, 2 percent of 79 is equal to 1.58.

In the prime factorisation of a perfect square in power format, all primes must be to an even power. 5688 = 23 x 32 x 79 To convert this it a perfect square, it needs the 2 and 79 to have an even power - the 3 is already at an even power. The smallest way to do this is to multiply 5688 by 2 x 79, ie multiply it by 158. 5688 x 158 = 23 x 32 x 79 x 2 x 79 = 24 x 32 x 792 = (22 x 3 x 79)2 = (948)2 = 898704
1/2 x 158 = 79
1 x 474, 2 x 237, 3 x 158, 6 x 79, 79 x 6 = 474
The prime factors are: 2 x 2 x 79

x2 + x + 20 = 0; a = 1, b = 1, and c = 20; use the quadratic formula x = [-b ± √(b2 - 4ac)]/(2a) x = [-1 ± √(12 - 4*1*20)]/(2*1) x = (-1 ± √-79)]/2 x = (-1 ± i√79)]/2 The solution set: {-1 - i√79, -1 + i√79}.
% rate: 79 1/2= 79.50 x 100%= 7950%
7.9 x 2 = 15.8
To find 2 percent of a number, multiply the number by 0.02. In this instance, 0.02 x 79 = 1.58. Therefore, 2 percent of 79 is equal to 1.58.
