Point Q is on line segment \overline{PR}
andrey2020 [161]

The numerical length of PR is 46

<h3>Line segment</h3>

Given the following segments

QR=2x+4

PQ = x

PR =4x -10

If Q is on line segment PR, then;

PQ + QR = PR

Substitute;

x+2x+4 = 4x - 10

3x - 4x = -10 - 4

-x = -14

x =14

PR =4x - 10

PR = 56 -10

PR =46

Hence the numerical length of PR is 46
