Answer:

N = Q/3  -  V

Step-by-step explanation:

Q = 2N + 3V solve for N

Subtract 3V from both sides

Q - 3V = 3N

Divide both sides by 3

(Q - 3V)/3 = N

Q/3 - V = N

or

N = Q/3  -  V

Prove ABCD is a parallelogram by showing both pairs of opposite sides are parallel, given the following points. Show all work!!!
bearhunter [10]

The prove that the angle ABCD is said to be a parallelogram that shows both pairs of opposite sides as parallel figure is given below.

<h3>What is the parallelogram  about?</h3>

The four points in the shape above are : A, B, C, D.

Where

A = (-2,-4)

B = (1,2)

C = (2,10)

D = (-1,4)

We place or sit vector AB with vector DC and vector AD  with vector BC

and so we find and place their coordinates.

vector AB (1-(-2), 2-(-4))

vector DC (2-(-1),10-4)

vector AD (-1-(-2), 4-(-4))

vector BC (2-1,10-2)

So we obtained:

vector AB (3,6)

vector DC (3,6)

vector AD (1,8)

vector BC  (1,8)

Next step is to calculate for the lengths :

AB=   \sqrt{3^{2} + 6^{2} }  DC= \sqrt{3^{2} + 6^{2} }

Thus, AB = DC

AD = \sqrt{1^{2} + 8^{2}  }     BC =\sqrt{1^{2} + 8^{2}  }

Hence one can say that  AD is equal to  BC.

Therefore, angle ABCD IS known to be a parallelogram .

grandymaker [24]

The volume of the rectangular pyramid with the given dimensions is: 1,890 cubic millimeters.

<h3>What is the Volume of a Rectangular Pyramid?</h3>

Volume of rectangular pyramid = 1/3(length × width × height)

Given the following:

  • Length = 21 mm
  • Width = 18 mm
  • Height = 15 mm

Volume of the rectangular pyramid = 1/3(21 × 18 × 15)

Volume of rectangular pyramid = 1,890 cubic millimeters.
