lions [1.4K]

Answer:

See below.

Step-by-step explanation:

Values are excluded if they make the denominator zero, so one rational expression could be:

(x^2 - 9) /  (x + 4)(x + 7)

- when x = -4 or -7 then the denominator is zero so the values of the function is undefined for these values.

denis-greek [22]

Answer:

Your answer is 8

Step-by-step explanation:

First you have to convert the mixed number into an improper fraction. To do this, multiply the denominator by the whole number. Then add the numerator and put that answer in a fraction over the original. So it would be 3*5=15+1=16/3. So now that the denominators are the same, all you need to do is see how many times 2 goes into 16. 16/2 which is 8. Answer = 8
