The equation is $\"\"$ .

Find the x-intercept..

The x-intercept is the value of x, when y = 0 \ \

$\"\"$ (Substitute y = 0 in original equation)

$\"\"$ (Multiply: $\"\"$ ) $\"\"$

Given that the x-intercept is

So,sustitute x = 2 in the derived equation $\"\"$ .

$\"\"$ (Substitute x = 2 in above equation)

$\"\"$ (Divide each side by 2)

$\"\"$ (Cancel common terms)

$\"\"$ (Divide: $\"\"$ )

The value of A is 10. $\"\"$

The option D is correct.
