-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
Answer:
Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are: Range. Interquartile range. Variability is the degree to which a data series deviates from its mean If you're going to spend money anyway, then why not get paid for it? <em>Hope This Answer Help Your Question Friend!</em>

Answer: Choice A
==========================================================
Explanation:
One shaded region is below the parabola, and the other shaded region is below the line. They both overlap outside the parabola, but under the straight line.
Since both shaded regions are below their respective boundaries, this means that we'll be using "less than" signs for each inequality. The solid boundary lines indicate "or equal to" is part of that as well.
Because of this, the answer is between A and D since both involve inequality signs that have "less than or equal to".
However, we can rule out choice D since the inequality 
would have the boundary line 
, and this boundary line has a positive slope. But notice how the red diagonal line slopes downward as we read from left to right. Therefore, the red line must have a negative slope. Luckily, choice A has one of the boundary lines as y = -x+3 to fit the description. So that's why choice A is the answer.
Answer:
Step-by-step explanation:
From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have
l = w + 3, where
l = length of the garden
w = width of the garden
Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as
W(w) = 2, where
W(w) = width of the garden.
That's all the parameters given in the question
