Question

If AB = x+ 4, BC = 2x -10 and AC

Answer 1

15

Explanation:

By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is
`3x-6`. Simplifying the equation
`3x-6=2x+1`, gives
`x=7`. Substituting
`x=7` in the equation for segment AC gives 15.
