Answer:
2
Step-by-step explanation:
The missing side of the right triangle is 2
6-6x= -24
Subtract 6 from -24 = -30
divide -30 by -6= 5
x=5
The answer is: She had more math assignments to start with, but completed more science assignments weekly.
For finding, the sum of last ten terms, we write the given AP in reverse order i.e, 126, 124, 122,..., 12, 10, 8
Hence,first term (a) = 126, common difference, (d) = 124 - 126
So,
![S _{10} = \frac{10}{2} [ 2a + (10 - 1)d ] \:](https://tex.z-dn.net/?f=S%20_%7B10%7D%20%3D%20%5Cfrac%7B10%7D%7B2%7D%20%5B%202a%20%2B%20%2810%20-%201%29d%20%5D%20%5C%3A%20)
![= 5 [2(126) + 9( - 2) ]](https://tex.z-dn.net/?f=%20%3D%205%20%5B2%28126%29%20%2B%209%28%20-%202%29%20%5D%20)
