1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula
to find the distance from point
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer:
.
Answer:
Option D is correct.

Step-by-step explanation:
Let V be the volume of hay in each stack
Given:
Length of the each stack is 
And Jay stores hay in cubic stacks on his farm.
The volume of the cone is.
Now, we substitute value of length of stack in above equation.



Therefore, the volume of hay in each stack is 
Answer:
The distributive property is when you take the value that the equation is being multiplied by and multiply each value in the equation by it.
Step-by-step explanation:
Ex.
3 ( 3 + 9 ) = ?
You can use the distributive property here:
<u>3</u> ( <u>3</u> + 9 ) = ?
<u>3</u> ( 3 + <u>9</u> ) = ?
( 3 x 3 ) + ( 3 x 9 )
9 + 27
36
3 ( 3 + 9 ) = 36
