C is the midpoint of AB. If AC = 2x + 18 and AB = 32, find x.

x = -1

Step-by-step explanation:

What we know: AC+CB=AB (Because midpoints create two equal segments), and AC=CB

With this equation, we can substitute the AC and AB with what we were given.

2x+18+CB=32

Since AC=CB, we can put CB as 2x+18 as well.

So now our equation is:

2x+18+2x+18=32  or 2(2x+18)=32

Now, we just have to simplify!

4x+36=32

4x=-4

x = -1

Hope this helped!

it is c, trust i got your back lol

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
