Answer:
There are two possible values: MN=5 or MN=19
Step-by-step explanation:
The points L and N are collinear, so we can visualize them on a right line as in Figure 1.
First suppose that M is between L and N as in Figure 2. Then we can compute the distance between L and N as LN=LM+MN. Substracting LM from both sides, we obtain that MN=LN-LM=12-7=5.
For the other possibility, suppose that M is not between L and N as in Figure 3. Because LM<LN, it's impossible that M is located further to the right than N. Then M isn't at the right of L. Therefore, M is at the left of L, so L is between M and N, so the distance between M and N is given by MN=ML+LN=LM+LN=7+12=19.

Answer:
<u>585 Cubic Meters</u>
Step-by-step explanation:
Since the room is in the shape of a rectangular prism, to find the volume, you'll do Volume = Length * Width * Height
So, 65 * 3 * 3 = 585 Cubic Meters
<em>(its in cubic meters because it is measuring a volume of space)</em>
Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We have the slope
and the point
.
Substitute:

- point-slope form
Convert to the slope-intercept form (y = mx + b):
<em> use the distributive property</em>
<em>add 4 to both sides</em>
- slope-intercept form
