Answer:

B. (5x - 4)(3x + 2)

Step-by-step explanation:

Factor the following:

\longrightarrow 15x² - 2x - 8

The coefficient of x² is 15 and the constant term is -8. The product of 15 and -8 is -120. The factors of -120 which sum to -2 are 10 and -12.

So,

\longrightarrow 15x² + (10 - 12)x - 8

\longrightarrow 15x² + 10x - 12x - 8

\longrightarrow 5x(3x + 2) - 4(3x + 2)

\longrightarrow (5x - 4)(3x + 2)

Which of the following is the best definition of vertical angles?
Lilit [14]

Step-by-step explanation:

Very quick and effortless example of vertical angles in the attached image. When 2 straight lines intersect, the 2 angles opposite each other at that point are vertical angles, and they are always congruent.

I'd say it's the 3rd option:

"Vertical angles are a pair of non-adjacent angles formed by two intersecting lines."

but any of the first three could be technically true really. Adjacent angles are 2 angles that share a side, and vertical angles cannot share one.
