Answer:

100

Step-by-step explanation:

You have to use the order of operation (PEMDAS) Paranthesis, Exponents, Multiplication, Division, Addtion, and Subtraction to solve this problem.

First, multiply 5 and 4 to get 20 since it's between paranthesis and get

40-(-40)+20

Then, add 40 and 40 as two negatives becomes a positive.  You should get

80+20

Finally, add 20 to 80 and get 100!

Which expression is equivalent to startfraction m minus 4 over m 4 endfraction divided by (m 2) ?
sertanlavr [38]

Rational functions are written as fractions. The expression equivalent to \frac{\dfrac{m-4}{m+4} }{m+2} is \frac{m-4}{m^2+6m+8}

<h3>Rational functions</h3>

Given the rational function expressed as:

\frac{\dfrac{m-4}{m+4} }{m+2}

This can be further expressed as:

\frac{m-4}{(m+4(m+2)}


Factorize the denominator to have;

\frac{m-4}{m^2+4m+2m+8}\\ \frac{m-4}{m^2+6m+8}

Hence the expression equivalent to \frac{\dfrac{m-4}{m+4} }{m+2} is \frac{m-4}{m^2+6m+8}
