Answer:
6 inches
Step-by-step explanation:
The volume of a triangular pyramid can be found using
v=1/3bh
where b is the area of the base, and h is the height
We know the volume is 12, so let's find the area of the base
The area of a triangle can be found using:
a=bh/2
We know the base is 4, and the the height is 3, so we can substitute them in
a=4*3/2
a=12/2
a=6
Now, we can solve for the height
v=1/3bh
Substitute 12 in for v, and 6 in for b
12=1/3(6h)
Multiply both sides by 3
3*12=1/3(6h)*3
36=6h
Divide both sides by 6
h=6
The height is 6 inches
Answer

Answer:
1800 liters
Step-by-step explanation:
150*150*80=1800000 cubic cm
1800000/1000= 1800 liters
Might seem like a lot but really isn't.
-2(x + 6) + 3 = -11x + 4(x + 4)
-2x - 12 + 3 = -11x + 4x + 16
-2x - 9 = -7x + 16
5x = 25
<em>x = 5</em>
Hope this helps! :)
