For x from A to B is from  2 to 14   distance = 12   we need 3 times this added to 14       x = 50

  for y    fro A to B is -2 to 4   distance = 6     3 times this added to 4   = 16                   y = 22

But how do you work it out?

Even squares come from even numbers

(x+2)^2  - x^2  = 228

x^2 + 4x + 4   - x^2 = 228

4x = 224

x = 56    x+2 = 58       58^2 = 3364

y = x^2 +10x - 7       when x = 0      you will have y intercept     = -7

                 when y = 0       you will have x-axis intercepts

   0 = x^2 + 10x-7    Use Quadratic Fomula to find x axis intercepts =  -5 +-  4 sqrt 2

Find a multiple of 5    plus 2    that leaves 3 when divided by 4

15 + 2       leaves    1   when divided by 4

20 +2       leaves two

25 +2       leaves 3        sooooo   27 stairs

4 ( x+7)(x+2)    expand

4 ( x^2 +9x + 14)

4x^2 + 36x + 56     is a bowl shaped parabola        max value =  + infinity

MIN value occurs at  - b/ 2a =   - 36/8 = - 4.5    use this value of 'x' in the equation to calculate the min value

10 people each have to play 9 other people = 90     BUT TWO people participate in each match   

                      so  90/2 = 45 matches

Solve the quadratic and take the positive root to get 10.175.

RS = 58-12 = 46.

Did you mean (2-x)? If you did, then the max is 81 at x=-5/2.

part a and part b are wrong :(

A) There are 50 matches.

B) There are 50 matches.

C) The fraction is 1/3.

3364. If we simply this problem to the differnce between 4^2 and 6^2, we see that the differnce is 20. This is basically eaual to the distance between 4^2 and 5^2 plus the distance between 5^2 and 6^2. To calculate the distance I use the formula (sq number, in this example 6 x 2-1), this means the distance from 5^2 to 6^2 is 11, and the distance from 4^2 to 5^2 is 9. We can also takeaway that the differenmce between squares is ALWAYS 2 greater than the last one. 

So, back to the problem, we can tell that the squares have to be 113 and 115 apart, which means that 2x-1=115, meaning that x = 58, doing the same thing to 113, means that x = 56. 

To check our answers, 58^2 is 3364, and 56^2 is 3136, the difference between these two is 228, meaning that our answer (58^2 or 3364) is correct!

A is the right answer. This is because option A is the only choice that contains all 3 points, T, S, and W. 

109 is the cirevt awnserrrrrrrr

D, a ray must have a dot on one side, and an arrow on the other, which means it goes on forever. Knowing that the endpoint must be Y, the dot must be Y. Since D is the only one that satisfies the question, D is the right answer

here

If the end point is Y, then there should be a dot at the Y and an arrow at the X.
