Answer:
15
Step-by-step explanation:
determine the numerical length of AC
We know that Ac is equaled to ab and bc because they are the segements between ac
3x 4x+8
A-----------------------------B----------------------------------C
|<----------------------------5x+10 --------------------------->|
AB + BC = AC
solving for x
3x + 4X + 8 = 5X + 10
3x+4x-5x= 10-8
2x=2
x=1
Now sub that in for ac
AC= 5x +10
AC= 5(1) +10
AC= 5 +10
AC = 15
Answer: is it -3,11
Step-by-step explanation:
For this case, we have the following expression:

We simplify the expression:
If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that 
So, we have to:

Answer:
-3x + x + 5 = -2x + 5
