Step-by-step explanation:

It is convenient to look at the differences of end point coordinates.

For a square, the values will be interchanged and one negated.

For a rhombus, the dot product will be zero.

For a rectangle, their sum of squares (diagonal length) will be the same.

1. VX = X - V = (11 -3, 4 -0) = (8, 4)

  WY = Y -W = (8 -6, 0 -4) = (2,-4)

The numbers are different, so it is not a square. The dot product is ...

 (8)(2) + (4)(-4) = 16 -16 = 0

So, the figure is a rhombus.

__

2. LN = (6 -1, 3 -2) = (5, 1); MP = (4 -3, 0 -5) = (1, -5)

The figure is a square.

__

3. HK = (12 -1, 0 -3) = (11, -3); JL = (3 -10, -3 -6) = (-7, -9)

The lengths of the diagonals are ...

  √(11^2 +3^2) = √130  and  √(7^2 +9^2) = √130

Diagonals are the same length, so the figure is a rectangle.

__

4. EG = (-2 -(-4), -1 -3) = (2, -4); FH = (-5 -(-1), 0 -2) = (-4, -2)

The figure is a square.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
