Answer: 
Step-by-step explanation:
Given : The total number of programmers in the company = 30
The company wants to select a group of 6 programmers to work on a particular project.
Since the order of selecting them does not matters , therefore we use combinations.
The number of combinations of r things taken from n things is given by :-
here, n= 30 and r= 6
So the number of different ways to form they could select a group of 6 would be 
i.e. Total ways =593775
In terms of factorials , the number of total ways to form they could select a group of 6 is .
Answer:
5 sides
Step-by-step explanation:
The quickest way to answer this is to use the fact the exterior angles of a polygon add to 360.
If the interior angles are each 108, then the exterior angles are each 180 - 108 = 72. (using the fact that the Interior angle + exterior angle adds to 180)
Next, we just work out 360 ÷ 72 = 5.
So the polygon must have 5 angles, and therefore 5 sides.

-4x^4 - 15x^2 + 1 - 19/x^2 is your answer
Hope I helped :)
Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
