Question

Helpppppppppppppppppppppppppp

Answer 1

We rewrite the expression:
 ((m-4) / (m + 4)) * (1 / (m + 2))
 Then we do the multiplication of fractions:
 ((m-4) / (m + 4) (m + 2))
 answer:
 An equivalent expression is:
 ((m-4) / (m + 4) (m + 2))
 option 1

Answer 2

Answer:
(m-4) / [(m+4)(m+2)]
This is the first option

Explanation:
The given expression is:
[(m-4)/(m+2)] / (m+2)

When dividing by a fraction, we convert the multiplication into division and flip the second fraction.
This means that the given expression can be written as:
[(m-4)/(m+4)] / (m+2) = [(m-4)(m+4)] * (1/(m+2)]
                                  = (m-4) / [(m+4)(m+2)]

Hope this helps :)
