Question

What is the distance between 4 and 17?

Answer 1

Answer:

14

Step-by-step explanation:

17 - 4 + 1 = 13 + 1 = 14

Answer 2

Answer:

Step-by-step explanation:

D = distance

$x_{1}$ = 4

$x_{2}$ = 17

No "y" values were given.

The distance formula:

$D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}$

If we insert in the values:

$D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}$

(0-0)^2 = 0 so we can just remove the last part since it's +0:

$D = \sqrt{(4 - 17)^{2}}$

4 - 17 is equal to -13:

$D = \sqrt{(-13)^{2}}$

Since $(-a)^{2} = (a)^{2}$, that means that the negative 13 becomes positive

$D = \sqrt{(13)^{2}}$

Now the square root and the square cancels each other out:

$D = 13$
