Write an expression in terms of x that represents the distance between ( 4 , 8 ) and ( x , 8 ) for x > 4 .

The distance between two points is the number of units between them

The expression that represents the distance between the points is x - 4

How to determine the expression

The points are given as: (4,8) and (x,8)

The distance (d) between points is calculated using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]d = \sqrt{(x - 4)^2 + (8 -8)^2}[/tex]

Evaluate the difference

[tex]d = \sqrt{(x - 4)^2 + 0^2}[/tex]

Evaluate the exponent

[tex]d = \sqrt{(x - 4)^2 + 0}[/tex]

Evaluate the sum

[tex]d = \sqrt{(x - 4)^2}[/tex]

Evaluate the exponent

[tex]d = x - 4[/tex]

Hence, the expression that represents the distance between the points is x - 4
