Move all terms containing C to the left side of the equation. -8c-11=21

Move all terms not containing C to the right side of the equation. -8c=32

Divide each term by -8 and simplify.

32/8 equals -4

C=-4

-4c - 11 = 4c +21 add 4c to both sides

 -4c - 11 + 4c = 4c + 21 + 4c simplify

- 11 = 8c + 21 subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21 simplify

- 32 = 8c divide both sides by 8

c = - 4

That's it

I hope you got the idea

15, Evaluate 6 choose 4.

Novosadov [1.4K]

Answer: The required result is 15.

Step-by-step explanation: We are given to evaluate the following :

"6 choose 4".

Since we are to choose 4 from 6, so we have to use the combination of 6 different things chosen 4 at a time.

We know that

the formula for the combination of n different things chosen r at a time is given by

$^nC_r=\dfrac{n!}{r!(n-r)!}.$

For the given situation, n = 6 and r = 4.

Therefore, we get

$^6C_4=\dfrac{6!}{4!(6-4)!}=\dfrac{6!}{4!2!}=\dfrac{6\times5\times4!}{4!\times2\times1}=15.$

Thus, the required result is 15.
