Answer:

y^2 + 8y + 16

Step-by-step explanation:

(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =

The first set of parentheses is unnecessary, so it can just be removed.

= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

= 6y^2 + 2y + 5 - 5y^2 + 6y + 11

Now you combine like terms.

= 6y^2 - 5y^2 + 2y + 6y + 5 + 11

= y^2 + 8y + 16

So I have to compute the following but i don't know what they mean any help?
Gelneren [198K]

Answer:

Step-by-step explanation:

This is a Combination (as in permutation vs combination) question the symbol (n r) refers to "n choose r". This is sometimes written as nCr

i.e the question is asking you to find how many combinations each will yield when you chose r items from n item without repetition and order does not matter.

I will only do the first question for you and you can just follow the same steps to solve the rest of the questions.

Recall that

nCr=\frac{n!}{(r!)(n-r)!}

Consider question a) we are given (5 1) or ₅C₁

we can see that n = 5 and r = 1

If we substitute this into the formula:

₅C₁ = (5!) / [ (1!)(5- 1)!]

= (5!) / [ (5- 1)!]

= (5!) / (4!)

= (5·4·3·2·1) / (4·3·2·1)

= 5

hence ₅C₁ = 5
