For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:

That means that the slope is -1.
ANswer:

6x² + 48x + 96
6(x² + 8x + 16)
6(x + 4)(x + 4) is your polynomial fully factored so I'm guessing the binomial you're looking for is (x + 4).
Answer:
The unit rate of 297 words for 5.5 minutes is, 54 words per minutes
hope this helps :-)
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
It’s c because if you look at it shows that it could do straight line
