By definition of the binomial coefficient,

so we have

as required.
N 2-1 < 3
n is equal to :
2-1 = 1 so n would have to be 1 in order to be less than 3
2 is the GCF 3+8k
Hope this answer helps you
Answer:
10.5
Step-by-step explanation:
Break the problem down into small parts:
2 to the power of 3= 8
8+7+6=
15+6=21
21/2
21 divided by 2 is 10.5
Hope this helps!
Let x represent the larger number.
Let y represent the smaller number.
x-y=4 Given
3x=5y-2 Given
Now we can just substitute; let x=4+y
Substitute 4+y for x in the second equation:
3(4+y)=5y-2
12+3y=5y-2
-2y=-14
y=7
Substitute back (into BOTH equations to double check work).
x, the larger number, is 11
