Answer:
approximately 42.05
Step-by-step explanation:
We know that the distance formula is
, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
x₂=3
y₂=8
x₁=21
y₁=-30
Then, we can plug it into the formula to get 
W 7ayat Omi 7atbha 12 it will be 12
Answer:
1.9099
Step-by-step explanation:
V = (PI) * r^2 * (h/3)
32 = (PI) * (16) * (h/3)
6/PI = h
1.9099 = h
If you would like to solve the equation x/2 + x = 3 for x, you can do this using the following steps:
<span>x/2 + x = 3 /*2
</span>x + 2x = 3 * 2
3x = 6
x = 6/3
x = 2
The correct result would be x = 2.
