$14$

$(10,0)$ and $(-4,0)$ are both points on the X-axis.

$(10,0)$ is $10$ units to the right of the Y-axis, and
$(-4,0)$ is $4$ units to the left of the Y-axis.

Therefore the points are $14$ units apart.

$14$

We can say that these are $14$ units apart because, they lie on the $x-ax$ $is$

(or)

$color(brown)(Dista$ $color(brown)(nce=sqrt((x_2-x_1)^2+(y_2-y_1)^2)$

Where (in this case)

$color(red)(x_1=10,x_2=-4,y_1=0,y_2=0$

Substitute the values in the formula

$rarrsqrt((-4-10)^2+(0-0)^2)$

$rarrsqrt((-14)^2+(0)^2)$

$color(green)(rArrsqrt(196)=14$
