Ned hello asap please

x=5

Step-by-step explanation:

a) A           B            C

  ...

b) If B is a midpoint then AB=BC,

4x+1=2x+11

c) Solving for x,

1. Subtract 2x from both sides:

4x+1=2x +11

-2x     -2x

so we get 2x+1=11

2. Subtract 1 from both sides:

2x+1=11

   -1    -1

so we get 2x=10

3. Device both sides by 2:

  2x/2=10/2, so we get

  x=5

d) Finding AC

AC= AB+BC

AB=4x+1

Plug in 5 instead of x;

AB= 4*5 +1

AB= 20+1

AB=21

AB=BC, so BC=21

AC=AB+BC

AC=21+21=42

AC=42

first one is a: renaming a fraction. second one is c: de-c
