Answer:
12
Step-by-step explanation:
Since M is a midpoint of LN, we can see 3x equal to x+8. Remove 1 x to get 2x=8. Solve for x to get x=4. Note that this is not the end to your problem. They asked for the length of MN, not the value of x. Plugging x into MN give you 4+8, which is 12.
(If you need to show work, here it is)
3x=x+8
2x=8
x=4
MN=x+8
MN=4+8
MN=12

!!!!!! What are the names of four coplanar points?
These points are all in the vertical plane shown in the diagram. Think of the plane as a flat sheet of paper that doesn't bend.
Only points L and K are outside of this plane. So if we listed {L, D, A, J} then that list of points isn't coplanar.
A, B, D, J points are all in the vertical plane shown. The plane as a flat sheet of paper that doesn't bend.
How to find if the point are coplanar or not?The points are not coplanar if there does not exist any plane that contains those points.
Only points are outside of this plane. So if we listed {L, D, A, J} then that list of points isn't coplanar.
Therefore a plane is formed by a line and one point outside of it.
Then, we need to select the last point in such a way that it lies outside of the plane generated by the first 3 points selected.
Thus, A, B, D, J
These points are all in the vertical plane shown. The plane as a flat sheet of paper that doesn't bend.

A dolphin is swimming 3 feet below sea level. It dives down 9 feet to catch some fish. Then the dolphin swims 4 feet up toward the surface with its catch.
What is the dolphin’s final elevation relative to sea level?
Answer:
The dolphin is -8 feet below sea level
Step-by-step explanation:
Start a -3 feet below sea level. Then subtract the -9 from when the dolphin dives. Then add the +4 feet. And you'll get -8. Hope this helps:)
The dolphin’s final elevation relative to sea level will be -8 feet.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a dolphin is swimming 3 feet below sea level. It dives down 9 feet to catch some fish. Then the dolphin swims 4 feet up toward the surface with its catch.
The elevation of the Dolphin is:-
Elevation = -3 - 9 + 4
Elevation = -8 feet
Therefore, the dolphin’s final elevation relative to sea level will be -8 feet.

The true statements about the lines in Trapezoid WXYZ are; Statements A, C, D and E.
How to define the properties of a Trapezoid?
The trapezoid showing the lines is seen online.
The given trapezoid is WXYZ. Now, in a trapezoid, one pair of opposite sides are usually parallel. Parallel lines have same slope and slope of line parallel to x axis is 0.
Now, If the line starts at the bottom left and goes towards the top right it means there is a negative slope. Thus, the true statments for Trapezoid WXYZ are:
- Line WZ has the same slope as line XY.
- Line XW has a lesser slope than line YZ.
- Line ZW has the same y-intercept as line WZ.
- Line XY has a greater y-intercept

–0.4|x + 5.75| – 4.3 = –8.7
The solution to the absolute value equation –0.4|x + 5.75| – 4.3 = –8.7 is
x = -16.75 or x = 5.25
The given absolute value equation is:
–0.4|x + 5.75| – 4.3 = –8.7
Collect like terms
–0.4|x + 5.75| = –8.7 + 4.3
–0.4|x + 5.75| = -4.4
Divide both sides by -0.4
|x + 5.75| = -4.4 / -0.4
|x + 5.75| = 11
x + 5.75 = 11
x = 11 - 5.75
x = 5.25
x + 5.75 = -11
x = -11 - 5.75
x = -16.75
The solution to the absolute value equation –0.4|x + 5.75| – 4.3 = –8.7 is
x = -16.75 or x = 5.25

Slope:
Use the slope formula:
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
(x₁ , y₁) = (0 , -2)
(x₂ , y₂) = (2 , -3)
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{-3 - (-2)}{2 - 0}[/tex]
Simplify. Note that if there are two negative signs directly next to each other, it becomes a positive sign:
m = [tex]\frac{-3 + 2}{2 - 0}[/tex]
m = [tex]\frac{-1}{2}[/tex]
Your slope is [tex]- \frac{1}{2}[/tex].
