The other root of the quadratic will be the conjugat of the given root...your polynomila will look like this:

(x - (3 + sqrt 7)) * (x-(3-sqrt 7))

= x^2    - 3x  + x sqrt 7     -3x    +9  - 3 sqrt 7  - sqrt 7x + 3 sqrt 7 - 7

= x^2 -6x +2         Now I think YOU can put in x = 2    to find the value in the numerator of your question

                               then put in x = 3 for the denominator.....   Let me know what you find !

(6x+4)(15x-?)

90x^2 + 60x -? 6x  - ? 4

If ? = 10

this becomes

90x^2 -40

5 through 100   (I think)    so  96 consecutive

  bearing = arctan (y/x) = 177.1 degrees

If the number ends in 24   44  52  56  64  72  76   it is divisible by 4  (throw out 44 ....can only use number onece) so 6 choices

Then the first number can be one of the other 5    i.e.  3 choices

  the second number then can be    one of 2   choices

6 x 3 x 2 = 36 possibles

8d +7r =13.60

7d +8r = 13.40    subtract second equation from first equation

d - r = .20

I've never seen a rooster that can lay eggs......perhaps it is a hen that IDENTIFIES as a rooster?   Haha  ! 

I will assume you mean the elevation in relation to sea level....

  I do not know why they gave you City A stats....sometimes Q's give information to mislead ya or to make sure you know what you are doing....

Part A       D_level = 1/4  C_level

            = 1/4 (-24) = -6 ft   which is the same as saying    = 6 ft BELOW sea level  (this is Part B)
