5(x-3) and 4x+3y-15-3y+x and -20-3x+5+8x
The numerical notation of 22000004 would be
2*10^6
6*5= 30 fingers, so tim would say there are 30 fingers.
If we take the square of x and square of y and then subtract them:
(csc t)²-(cot t)²=1 ( this eq. gets from basic identity
x²-y²=1......a 1+cot²x=csc²x)
equation 'a' represent the equation of hyperbola which is (x²/a²)-(y²/b²) =1 with given conditions( a=1,b=1)
So, option D is correct
