The distance between the lines is d=\frac{7}{3\sqrt{34}}  unit.

Step-by-step explanation:

Given : Lines 5x + 3y -7 = 0 and 15x + 9y + 14 = 0

To find : Distance between the lines ?

Solution :

The formula of distance between two lines a_1x+b_1y+c_1=0 and a_2x+b_2y+c_2=0 is given by,

d=|\frac{c_1}{\sqrt{a_1^2+b_1^2}}|+|\frac{c_2}{\sqrt{a_2^2+b_2^2}}|

On comparing, a_1=5,b_1=3,c_1=-7,a_2=15,b_2=9,c_2=14

Substitute the values,

d=|\frac{-7}{\sqrt{5^2+3^2}}|+|\frac{14}{\sqrt{15^2+9^2}}|

d=|\frac{-7}{\sqrt{25+9}}|+|\frac{14}{\sqrt{225+81}}|

d=|\frac{-7}{\sqrt{34}}|+|\frac{14}{\sqrt{306}}|

d=|\frac{-7}{\sqrt{34}}|+|\frac{14}{3\sqrt{34}}|

d=|\frac{-21+14}{3\sqrt{34}}|

d=|\frac{-7}{3\sqrt{34}}|

d=\frac{7}{3\sqrt{34}}

Therefore, the distance between the lines is d=\frac{7}{3\sqrt{34}}  unit.
