Plug in 4 for the value of x.
f(4)= 1/2(4)-2
f(4)= 2-2
f(4)= 0
Final answer: 0
Choice A - Octahedron is the answer
Answer:
Length of BD =
+6x - 40
Step-by-step explanation:
In parallelogram ABCD , diagonals AC and BD intersect at E .
In a parallelogram , the two opposite sides are parallel and equal in length.
Also opposite angles of a paralleogram are equal .
Here the length of the parts of a diagonal is given.
BE =
- 40
DE = 6x
Since the length of whole diagonal is the sum of the lengths of the parts of the diagonal ,
Length of BD = BE + DE
=
-40 + 6x
Length of BD =
+6x - 40
The answer is most likely 28.2843
