what about
15 1
13 3
11 5
9 7
You did good GS....it is just that the median is x + 13 (the 14th number in the 27 number sequence )
USe distance formula
(2a-4)^2 + (a-4 - -1)^2 = (2 sqrt10)^2
4a^2 - 16a + 16 + a^2 -6a +9 = 40
5a^2 - 22a -15 = 0 quadratic formula shows a = 5 or - 0.6 you can take it from here
Remember sqrt (-1) = i ?
3 + sqrt (-16) =
3 + sqrt (16*(-1) ) = 3 + 4i
and 6-sqrt(-64) = 6 - 8i take it from here ............
x = .abababab....
100x = ab.ababab...
100x - x = 99x = ab
x = ab/99 ab can be 64 choices if they ab is 1 3 or 9 11 or 33 the denominator could be 99 33 or 11 9 or 3
so I THINK the answer is 5
Angle 4 and angle 2 are equal soooo...
x+30 = 2x+15 solve for 'x' then angle 4 = x+30
Straight line = 180
180 = 4x+30 + 8x+90 solve for 'x' then MON = 8x+90 o
Using 'addition method'
Welllll...... those two equations are the SAME line....infinite answers....is this a trick?
(x, 4/3-2x)
That is it....you did it 2/25 - 14/25 i
Equate the two equations and solve for x = + -1
at 1 y =3
at -1 y = 1 so max diff = 3-1 = 2
