Is there a picture to go along with it? Because it's asking for the measure of ABD which is a triangle or a ray or something
fg^3 / g^3f = 1
f^4 / f*f*f*f = f^4 / f^4 = 1
f^2g^3 / f^3g^2 = g/f
f*f/f^2 = f^2 / f^2 = 1
Answer:
f^2g^3 / f^3g^2
Answer:

Step-by-step explanation:
You can use the work they gave you and continue from there:

First, simplify the numerator:

Finally, simplify the denominator:

Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
