Answer:
10x+9
Step-by-step explanation:

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.
2x(2x + 3)
That would be -----------------------
2x^2 + 13x + 15
We should factor the denominator and then reduce the original fraction:
2x(2x + 3) 2x x
----------------------- = ------------- = ---------
(2x + 3)(2)(x+5) 2(x+5) x+5
This is true only for x not equal to -5, not equal to -3/2.
No table that shows that is posted with the question.
