Answer:
Hi there!
Your answer is two times.
Step-by-step explanation:
The distributive property is multiplying the coefficient in front of parentheses into the parentheses. You have two sets of parentheses both with a coefficient that needs to be distributed.
The first time you use it is on 2(x+5), distributing the 2.
The second time you use it is on the -3(2x+7), distributing the -3
Please let me know if you have questions :)
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
