What is the coeffieent of (x^4)(y^4) in the expansion of (x+y)^8?

70 is the required coefficient.

Step-by-step explanation:

We have been given

Using the general formula which is:

Here, n=8 now, substituting the values in the formula we get:

So, we want coefficient of

Coefficient is multiple with the term we need to find coefficient of.

is coefficient of

Using

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
