1, 9, 36, 84, 126, 126, 84, 36, 9, 1.

Step-by-step explanation:

Using the binomial theorem:

(x + y)^9 = x^9 + 9C1 x^8 y + 9C2 x^7y^2 + 9C3x^6y^3 + 9C4x^5y^4 + 9C5x^4y^5 +

9C6x^3y^6 + 9C7x^2y^7 + 9C8xy^8 + y^9

The coefficients are

Simplify (3xy2)(4xy)(2xy)3. 24x3y2 24x5y6 96x5y6 96x3y3

Oliga [24]

(3xy^2)(4xy)(2xy)^3 = (3xy^2)(4xy)(8x^3 y^3) = (3*4*8)x^(1+1+3)y^(2+1+3) = 96x^5y^6

What is an example of when you might need to use decimals and other rational numbers in everyday life?

nignag [31]

Well, in the store, when you buy something, there are decimals, also, speed limit for your car, and time, but that is not an exact thing for this question, because 60 can't be a decimal. you cant make it so you can show 60 seconds as a decimal without an irrational number. sometimes, the number just goes on forever.

jamie volunteers at the pet shelter every 3 days and at the food pantry every 6 days. this month he volunteers at the pet shelte

denpristay [2]

Answer: No. Jamies reasoning doesn't make any sense.

Counter example :- Isha decides to go on walk on every 4th day and go for gym on every 2nd day in a month.

Then Isha will do both the things on same day = LCM (4,2)

Now, LCM of 4 and 2 = 4

Therefore, Isha will do both the things on 4th day of the month .

Step-by-step explanation:

Jamies reasoning doesn't make any sense.

Because the LCM of 3 and 6 = 6 not 18[since 6=3×2]

LCM is the least common multiple number of two or more numbers.
