Since
$18x^3=2\cdot 3\cdot 3\cdot x\cdot x\cdot x \\ \\ 30x^5=2\cdot 3\cdot 5\cdot x\cdot x\cdot x\cdot x\cdot x$
you can see that common expression is
$2\cdot 3\cdot x\cdot x\cdot x=6x^3$ .
Answer: Correct choice is A.

What is the slope line through (-9,-6) and (3,-9)?

chubhunter [2.5K]

Answer:

-1/4

Step-by-step explanation:

We can find the slope of the line given two points

m = (y2-y1)/(x2-x1)

= (-9- -6)/(3- -9)

= (-9+6)/(3+9)

=-3/12

= -1/4

G(n)=n^3+n g(-3) help!

Svetradugi [14.3K]

The question is simply asking you to evaluate the function for an input value of -3. Meaning we plug in -3 for all cases of n. (-3)^3 + (-3). This gives us -27 -3 which is -30. So g(-3)= -30
