Gthe sixth row of pascal's triangle is: 1 6 15 20 15 6 1 (a) what is the 7th row of pascal's triangle? (b) use your answer to the previous problem to write the expanded form of (x + y)7.

ANSWER

a)The 7th row is:

1 7 21 35 35 35 21 7 1

b)

EXPLANATION

The sixth row of Pascal's Triangle is:

1 6 15 20 15 6 1.

We generate the 7th row by repeating the eXtreme 1s and adding the entries directly above to generate the entries within as show in the attachment.

The 7th row is:

1 7 21 35 35 35 21 7 1

b) We can use this to expand

We know that the degree of x is going to decrease from left to right and the degree of y is going to increase from left to right.

This simplifies to,

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

yes
