A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices. 

In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m

We sketch a diagram of a tetrahedron with the given measurement as shown below

To find the height, we will use the Pythagoras theorem

20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)

nlexa [21]

Answer:

4x^2-16x-20

Step-by-step explanation:

(x-5)(x+1)=x^2-5x+x-5=x^2-4x-5

leading coefficient=4

which means that 4(x^2-4x-5)=4x^2-16x-20 is the answer.
