Answer:

Step-by-step explanation:

It is made with a combination. Combination of 4 taken from 8, the formula of the combination is as follows:

nCr = n! / (r! * (n-r)!)

In this case 8 is "n" and 4 is "r"

8C4 = 8! / (4! * (8-4))!

8C4 = 8! / (4! * 4!)

8C4 = 40320/576

8C4 = 70

In this way he obtained the answer that is 70

Simplify x^2-9x-22/x-11

OleMash [197]

Answer:

x^2-11/-8x

Step-by-step explanation:

We can solve this equation easily by using PEMDAS, or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first left to right)

Addition>Subtraction (See multiplication>division)

Now that we know the order of the operations, we can solve.

First, we cant solve for x^2 because we dont know the value of x, so well leave that alone. Same with 22/x. All we can do is use the commutative property.

So our equation is now x^2-11/-8x

Hope this helps!
