Question

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

Answer 1

Answer:

15

Step-by-step 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.
