If we assume that point C is somewhere on segment AD, then,

AD = AC + CD

AD = (9x-12) + (4x+18)

AD = (9x+4x) + (-12+18)

AD = 13x+6 is the answer

Hey!

First, let's write the problem.
$2-\left(-8\right)+\left(-3\right)$
We know that, $-\left(-8\right)=+8$ , so let's apply that
$=2+8+\left(-3\right)$
We have to add, $2+8=10$
$=10+\left(-3\right)$
We know that $+\left(-3\right)=-3$ , so let's apply that.
$=10-3$
Subtract. $10-3=7$
$=7$

Our final answer would be 7!

Thanks!
