  • four triangular faces,
  • six edges
  • four vertex corners.

Among the four faces, any one of them can be considered to be the base of the pyramid.

The faces are of equal shape and size.

The expression -2\vec C+6\vec D in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is a \vec i+b \vec j.

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression  -2\vec C+6\vec D = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16)  in the ordered pair notation.

That is, the vector \bold {-2\vec C+6\vec D} is a vector with x-component 16 and y-component -16.
