The second term of the expansion is 
.
Solution:
Given expression:
To find the second term of the expansion.
Using Binomial theorem,
Here, a = a and b = –b
Substitute i = 0, we get
Substitute i = 1, we get
Substitute i = 2, we get
Substitute i = 3, we get
Substitute i = 4, we get
Therefore,
Hence the second term of the expansion is .
Answer:
X=70
Step-by-step explanation:
Interior angles of parallel line sum up to be 180° so:
45+(2x-5)=180
45+2x=185
2x=140
x=70
Okay so this is a wild guess but I would say 12. The whole angle is 90, but only 1/3 of that is in the smaller portion of the triangle. So, I assumed that 1/3 of the length of the whole triangle. Three times 6 is 18 and minus AD is 12. So BD=12? This is my best guess hope it helps
