T = 4h 
When H = doubled (* 2)

T = 4(h * 2)
T = 4(2h)
T = 8h

If : H = 2
on first equation:
T = 4(2)
T = 8

on second equation:
T = 4(2 x 2)
T = 4(4)
T = 16

The value of "T" will raise up or it will become 8 multiplied by h or 8h.
The answer is A. Doubled, since on first it is "4h" then at the end it became "8h", by which 4 x 2 = 8.

2. Y = k / x
    Y = k / 3x
     
When k = 2 and x = 2
on first equation:
Y = 2 / 2
Y = 1

on second equation:
Y = 2 / 3(2)
Y = 2 / 6
Y = 1 / 3

The answer is definitely letter D, on the first equation: Y = k / x when variables k and x are 2, the answer is 1, on the second equation: Y = k / 3x when variables k and x are 2, the answer is 1 divided by 3.

3. Don't know the solution. :)
