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)
I think its 72 cause 8x3 is 24. and then 24x3 is 72.. let me kniw if im right!
Answer:
Irrational:
3√25, √256, √141
Rational:1.1625, 5.516...
Step-by-step explanation:
<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations
-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>
