Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
9 ≤ 17 - 4x
9 - 17 ≤ 17 - 17 - 4x
-8/-4 ≤ - 4x/-4
x≤ 2
hope this helps

The magnitude of intensity 
of light varies inversely as the square of the magnitude of distance D from the source.
That is
Then,
Given that,
The magnitude of intensity of illumination on a screen 56 ft from a light is 2.7 foot-candle.
Here,
=2.7 foot-candle, 
= 56 ft
=?, 
= 70 ft.
foot-candle
The intensity on a screen 70 ft from the light is 1.728 foot candle.
