1 = x + 4
3 = x
2 = 2x + 5
3 = 2x
3/2= x
You divide both sides by pr to get t on one side.
1=prt
= 1/pr=t
So the answer is one as the numerator and pr as the denominator
1/pr
Cotx = cosx/sinx
cscx = 1/sinx
If we plug these into your equation we get:
(cosx/sinx)/(1/sinx) - 1
Dividing by a number is the same as multiplying by its reciprocal so it can be rewritten as:
(cosx/sinx)(sinx) - 1
The two sinx's cancel each other out so we end up with cosx - 1
Since 3 divides 42, 3xy itself is the greatest common factor of 3xy and 42xy.
Answer: 3xy
