$\dfrac{x+2}{x^2-6x-16}:\dfrac{1}{9x}=\dfrac{x+2}{x^2-8x+2x-16}\cdot9x=\dfrac{x+2}{x(x-8)+2(x-8)}\cdot9x\\\\=\dfrac{x+2}{(x-8)(x+2)}\cdot9x=\dfrac{1}{x-8}\cdot9x=\dfrac{9x}{x-8}$

"9 less than a number is<br> zero." <br> I need help

zysi [14]

Answer:

Step-by-step explanation:

Less means minus, so basically X ( something ) - 9 is 0

X - 9 = 0

You add 9 on each side

X = 0 + 9

X = 9

Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:

0 + 9 = 9

Hence the number is 9

( sorry if I misunderstood )
