Answer:
true
Step-by-step explanation:
For 3 sides to be able to form a triangle, we need to check that the 2 shorter sides can "touch" when "stemming" out of the long side.
The long side has length 7cm, so the sum of 2 shorter sides must be bigger than 7cm for them to "touch". Note: if the sum was 7cm, the only way they would touch is if they were laid along the long side, so it would not be a triangle - it would be a segment.
Fortunately, 3cm + 5cm > 7cm, so we can form a triangle.
Since they pick 3 quarts in 1 hour they can pick 6 quarts in 2 hours and 9 quarts in 3 and so on. So the number of quarts they can pick in a certain amount of hours is just the total number of hours they spend picking times 3 quarts. So since they picked for 7 hours and each of those hours they picked 3 quarts, in total they picked 21 quarts
7 x 3 = 21 quarts
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,
