Answer: 9 (2x + 1)
Step-by-step explanation: i hope i helped
So (f-g)(x) = 3x2 + x, so when x = 2, the function is 14
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10 |subtract 2 from both sides
3x = 5x - 12 |subtract 5x from both sides
-2x = -12 |divide both sides by (-2)
x = 6
