Answer:

A = - 2n - 1

Step-by-step explanation:

A=-3+(n-1)(-2)

<=> A = - 3 - 2(n-1)

<=> A = - 3 - 2n -2×(-1)

<=> A = - 3 - 2n + 2

<=> A = - 1 - 2n = - 2n - 1

Which expression represents the number of possible combinations of n items taken rat a time
Likurg_2 [28]

Answer:

nCr =  n! / (r!)(n-r!).

Step-by-step explanation:

That would be nCr =  n! / (r!)(n-r!).

A quick way of working these out is as follows:

Take 7C4:

this  is  7*6*5*4/4*3*2*1   Cancelling out the 4 and 3*2:

=  7*5

= 35.

15C12 = 15C(15-12)

= 15C3

= 15*14*13 / 3*2*1

=  5*7*13

= 455.

I need to solve for X btw they are same side interior ( supplementary angles )​
Sidana [21]

Answer:

x = 17.2

Step-by-step explanation:

since they are supplementary, when you add then together they equal 180

4x + 8 + 6x = 180

Combine like terms

10x + 8 = 180

subtract 8 from both sides

10x = 172

divide each side by 10

x = 17.2

hope this helps :)
