Answer:
8) - 8z^3 - 3z^2 - 2z + 13
9) g^3 - 3g^2 + 3g + 6
10) (14n + 21) - (8n + 7) = 6n + 14
Howdy!
The answer is A, Between 2 and 3. To find this out, multiply 6(/1) by 2/5, which is 2.4, 2.4 is between 2 and 3, so that's the answer.
Hope this helped!
Sorry don’t now the answer to this problem
Answer:
See below
Step-by-step explanation:
Here is one way .... I showed you how to use Law of cosines in another Q
use this to find CB
CB^2 = 13^2 + 21^2 - 2(13)(21) cos 91 <==== solve for CB
THEN use law of SINES to find angle B
sin B / 21 = sin 91 / CB (CB you found using law of cosines above)
