Answer:
The answer is cscx(cscx - 1) ⇒ the second answer
Step-by-step explanation:
∵ csc²x = cot²x + 1
∴ 
Multiply the fraction by its conjugate 1 - sinx (up and down)
∴ 
∵ 1 - sin²x = cox²x
∴ 
∵ cot²x = cos²x/sin²x
∴ 
Take cscx as a common factor
∴ cscx(cscx - 1)
4y - 3 = y + 6
Add 3 to both sides
4y = y + 9
Subtract y from both sides
3y = 9
Divide both sides by 3
y= 3
13.2*3.9 =51.48
51.48*6= 308.88
This rounds to 308.9 cm^3
Hello!
First we have to find out how much each copy cost
240 / 60 = 4
Since each magazine cost $4 the answer is y = 4x; (1,4), (2,8), (3,12)
Hope this helps!
