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.
Answer: 32
Step-by-step explanation:
2^2 is 4
2^-3 = 1/8
and 4/1/8 is 32
Answer:
384 cubic meters
Step-by-step explanation:
Think of it as two rectangles on top of each other and then add the two volumes.
Volume is l*w*h
So for the bottom rectangle: (8) (12) (2) = 192 cubic meters
And for the top rectangle: (4)(6)(8) = 192 cubic meters
It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.
Then you add them together.
192+192 = 384 cubic meters
20ml = 80ml / 4 = 380/4 = 95 mg
Flow rate: 95 mg / hr
