Simplify the expression 6C2
iVinArrow [24]

Answer:

^6C_2=15

Step-by-step explanation:

Recall the formula:

^nC_r=\frac{n!}{(n-r)!r!}

We apply this formula to simplify ^6C_2

This implies that:

^6C_2=\frac{6!}{(6-2)!2!}

^6C_2=\frac{6!}{4!2!}

^6C_2=\frac{6\times5\times4!}{4!\times 2\times1}

This simplifies to

^6C_2=\frac{6\times5}{2\times1}

^6C_2=\frac{3\times5}{1\times1}=15

Solve for x: 2(2a+3)-6=5a+2
coldgirl [10]

Answer:

a=-2

We move all terms to the left:

2(2a+3)-6-(5a+2)=0

We multiply parentheses

4a-(5a+2)+6-6=0

We get rid of parentheses

4a-5a-2+6-6=0

We add all the numbers together, and all the variables

-1a-2=0

We move all terms containing a to the left, all other terms to the right

-a=2

a=2/-1

a=-2

Step-by-step explanation:

We move all terms to the left:

2(2a+3)-6-(5a+2)=0

We multiply parentheses

4a-(5a+2)+6-6=0

We get rid of parentheses

4a-5a-2+6-6=0

We add all the numbers together, and all the variables

-1a-2=0

We move all terms containing a to the left, all other terms to the right

-a=2

a=2/-1

a=-2
