Answer:
The answer is 10x - 10y - 9
Step-by-step explanation:
14 - 3 - 20 = -9
2y - 12y = -10y
7x + 3x = 10x
14 + 2y - 3 + 7x - 12y + 3x - 20 = 10x - 10y - 9
It is the formula to find the longest line on a right triangle. for example, a squared plus b squared equals c squared. In this case, c must always be the line not relating to the right angel.
Part a .
A arithmetic sequence with a third term of 8 and a common difference of 5 .
To find the first five therms, since the common difference is 5, so we add 5 to get the fourth term and add 5 to fourth term to get the fifth term .
And for first two terms, we will subtract 5 from 8 to get the second term and subtract 5 from the second term to get the first term. And we will get

Part b:A geometric sequence with a fifth term of 1/3 and constant ratio of 1/3.
TO find the first five terms, since the constant ratio of 1/3, so we multiply 1/3 to third term to get fourth term, and multiply fourth term by 1/3 to get fifth term .
And to get the first two terms, we will divide third term by 1/3, to get the second term and divide the second term by 1/3 to get the first term, that is
