The inequality described can be written as:
y < 3x + 2.
<h3>How to get the inequality?</h3>First, we know that we have a dashed line, and the region to the left of that line is shaded, then we will have:
y < line.
The linear equation is of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
Remember that if a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope is:
Here we know that the line passes through (-3, -7) and (0, 2), so the slope is:
And because the line passes through (0, 2), the y-intercept is 2, then the inequality is:
y < 3x + 2.

Answer:
<em>A(x) = 6x² + 26x </em>
Step-by-step explanation:
A(x) = 4x ( x + 10 ) - 2x ( 8 ) + +
A(x) = 4x² + x² + x² + 40x - 16x + 2x
<em>A(x) = 6x² + 26x</em>
