My boiii, tiger algebra helped me out a little on this one, I got 7c * sqrt(5)
Answer: The 20th term is 100
Step-by-step explanation: It adds by 6 each time
-14, -8, -2, 4, 10, 16, 22, 28, 34, 40, 46, 52, 58, 64, 70, 76, 82, 88, 94, 100
Answer:
-28 = x
Step-by-step explanation
[5x + 20] + [4x - 8] = 180
9x + 12 = 180
- 12 -12
______________
9x = 168
18⅔ = x
m∠EBC = 5[18⅔] + 20 = 113⅓
93⅓
You will get a negative answer if you set them equal to each other, which is not allowed when you are talking about <em>length</em><em>.</em>
I hope this is correct, and as always, I am joyous to assist anyone at any time.
