I think there's something missing.
- 3 (- 2 + 9v) = (-3)·(-2) + (-3)·(9v) = 6 - 27v

2. you should get 170
Comment : i see you are dividing 170 by 12. Yea , don't do that. convert 12 into a decimal. for that all you have to do is move the
decimal 2 times to the left. (always do that)
3. Now that you know that multiply 170 and 0.12.
4. you should get 20.4 students, but round it to 20 students
Answer: 20 students voted for Mrs.Alberto
Answer:
-25/8 I think
Step-by-step explanation:
[9tan(θ) * 9cot(θ)] / 9sec(θ)
First cancel out the 9's:
tan(θ)cot(θ)/sec(θ)
Recall the following trig identities:
tan = sin/cos
cot = cos/sin
sec = 1/cos
Thus, we can rewrite the expression as:
[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))
In the numerator, the sine's and cosine's cancel each other out:
1 / (1/cos(θ))
which we can rewrite as cos(θ).
