Answer:
57
Step-by-step explanation:
if 1 = 123 degrees, and the angles add up to 360, then 6 would be 57. Because you would do 123 is 5 and 8, and so 246 is adding those angles. So now you have 7 and 6. 360 - 246 is 114, and since 7 and 6 are equal, just divide that by 2
Answer:
D: b^8
Step-by-step explanation:
b^10/b^2 becomes slightly clearer if written as:
b^10
--------
b^2
To obtain the correct exponent here, subtract 2 from 10, obtaining 8:
b^10
-------- = b^8
b^2
Answer D is correct.
11 836/1000. Simplified: 11 209/250.
I hope this helps! :)
A, C, and E seem all right. In letter form: 1st 3rd and 5th
Answer: 4a^2-2b^2 (I think this is right)
Step-by-step explanation:
Using the order of operations I started by multiplying both of the sides separately. The left side of the equation becomes 2a^2-b^2-ab while the right becomes 2a^2-b^2+ab. Then I put the sides together to add them and after combining like terms it becomes 4a^2-2b^2.
