Answer:
14 units
Step-by-step explanation:
The angle bisector divides the sides proportionally, so you have ...
(x+4)/8 = (2x+1)/12
3(x +4) = 2(2x +1) . . . . . . multiply by 24
3x +12 = 4x +2 . . . . . . . . eliminate parentheses
10 = x . . . . . . . . . . . subtract (3x+2)
Then BD = x+4 = 10 +4.
The length of BD is 14 units.

<em>Additional comment</em>
The "triangle" cannot exist, as the side lengths are shown as 8, 12, and 35. The long side is too long. Nice math; bad geometry.
Division Property of Equality
Answer:
See below.
Step-by-step explanation:
(Given)
(Subtracted 3 on both sides)
(Subtracted ax on both sides)
(Factor out x from x - ax)
(Divided 1 - a on both sides)
(y^2 + 7y +12) / (y^2+8y +15)
factor both equations:
(y+3)(y+4) / (y+3) (y+5)
cancel out common factors to get:
y+4 / y+5
Answer:
x > 0
Step-by-step explanation:
If is open circle it means is less than or greater than and if is closed circle it means that is less than or equal too or greater than or equal too. In this case the circle is open so it means that is less than or greater than and the only symbol available in the answer choices is greater than. So you will be stuck with the first and second option. The answer will be x > 0 because the line is going to the right meaning that x is greater than 0. Hope this helps!!
