Answer 1

(4x+16)/(x^2-16) * (x-4)/x ?

Answer 2

yes

Answer 3

You need to simplify each term first. What can 4x+16 be written as?
Similarly, what can x^2-16 be written as? Then, cancel out same terms when they occur in numerator and denominator.

Answer 4

Factor out 4 from 4x+16= 4(x+4)
For x^2-16 use difference of squares =(x-4)(x+4) and follow GT instructions

Answer 5

i got x+4 over x... or is it x+4 over 4x

Answer 6

It should be 4/x.

Answer 7

4(x+4) * (x-4) / (x+4)(x-4)x = 4/x
