Final answer:
By substituting m=4 into the expression (4m+8)/(4m+4) and simplifying, we find that the value of the expression when m=4 is 6/5.
Step-by-step explanation:
The question asks us to find the value of the expression (4m+8)/(4m+4) when m is equal to 4. To solve this, we simply substitute the value of m into the expression:
(4(4) + 8) / (4(4) + 4) = (16 + 8) / (16 + 4) = 24/20.
Now, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
24/20 = (24/4) / (20/4) = 6/5.
Therefore, the value of the expression when m = 4 is 6/5.
