Student B is wrong , student A is correct in simplifying the expression .
Expression B must be simplified to cot θ .
Formulas to be used are :
1 - 
θ = 
θ
1 - 
θ = 
θ .
Since , location of error is step 3 , we will start from there
[ ( 1 - θ ) / sin θ ] / cos θ = [ ( 1 - θ ) / sin θ ] * [ 1 / cos θ ]
= ( 1 - θ ) / ( sin θ * cos θ )
= θ / ( sin θ * cos θ )
= cot θ .

Since , the question is incomplete we assume it to be :
Answer:
Step-by-step explanation:
-4 ( 4v - u - 6 )
You will multiply -4 with everything in the parentheses.
-16v + 4u + 24

Step-by-step explanation:
3x + 14 = 23
3x=23-14
3x=9
x=9/3
x=3
option A is the correct answer
Answer:
$356.00
Step-by-step explanation:
If d represents the discounted price, and p is the original price, you have ...
d = p - 20% × p = p(1 -20%) = 0.80p
Then the original price is ...
p = d/0.80 . . . . . divide by the coefficient of p
p = $284.80/0.80 = $356.00
The price before the discount was $356.00.
