To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
You just put all of the like terms together, if it has an X combine it and if it doesn't have an X combine it. You end up with 4x-5

Answer: Choice B</h3>
Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
=======================================================
Explanation:
Recall we have these rules
- positive times positive = positive
- positive times negative = negative
- negative times negative = positive
Here is one example for each rule
- 8*7 = 56
- 5*(-9) = -45
- -2*(-4) = 8
So based on that, we know that (-5)(-3) is positive. The two negatives cancel each other out so to speak. The same goes for (-8)(-6). Then multiplying any two positive numbers produces another positive outcome.
