x/(sqrt(x) + sqrt(y)) = 18 and y/(sqrt(x) + sqrt(y)) = 2.

x = 18 *(sqrt x sqrt y)        y = 2(sqrtx+ sqrty)                        Multiply 2nd equation by -9  then add both equations...

                                       -9y = -18 (sqrtx+ sqrty)

x-9y = 0       x = 9y

y = 2 (sqrt(9y) + sqrty)

         y=2 sqrty (sqrt 9+1) 

          y = 8 sqrty

          y^2 = 64 y

          y= 64

                       x = 9y = 576              

Where is the drawing?

I, for one, do not know, Darry !  Looks like you NOW have 14 ......

z^4 = -4

z^2 = +- sqrt(-4) = +-2i

z = +- sqrt(+-2i)

=  -1+i  ,   -1-i    ,  1-i    ,  1+i 

y + 2x = -19

y = -2x - 19          this is DIRECT variation    k = -2      

(EXAMPLE of INdirect variation would be something of THIS nature  y = -2/x - 19  )

Yes, it will fit diagonally....

3¹ x 3¹ x 3¹ x 3¹ = 3^(1+1+1+1)= 3⁴

Well, yes....there is only one.    Which one?   Substitute x = 2     and then x = 6 into the original equation to see which one works.

Total candies = 16

First red  4/16

Now there are only 3 red out of 15

Second red = 3/15

Third red = 2/14

4/16 * 3/15 * 2/14   =  ??
