Answer:
They can have infineyely many solutions :)
Both expression have the same denominator: 9x²-1. Thus it must not be 0.
9x²-1=(3x-1)(3x+1)=0, resulting x=+-1/3.
Restrictions: x in R\{-1/3, 1/3}
Adding those expressions:
E=(-x-2)/(9x²-1 ) + (-5x+4)/(9x²-1)=
(-x-2-5x+4)/(9x²-1)=(-6x+2)/(9x²-1)=
(-2)(3x-1)/(9x²-1)=-2/(3x+1)
E=-2/(3x+1)
Answer: the answer is: 60π in²
Step-by-step explanation:
Lateral surface area for a circular cone is given by the formula in the attached picture.
Lateral Surface Area,
=πr √( r² + h²)
=π (6) √( 6² + 8²)
= π6 √( 36 + 64)
= 6π √(100)
= 6π (10)
= 60π in²
