Determine the formula, in terms of x, that best describes the area of the plot.
1 answer:
The area of a plot is the amount of space on the plot
The area of the plot is 2x^2 -x - 1
<h3>How to determine the area</h3>The dimensions of the plot are given as:
Length=2x+1
Width=x-1.
The area of the plot is the product of its dimension.
So, we have:
Expand
Evaluate the like terms
Hence, the area of the plot is 2x^2 -x - 1

Step-by-step explanation:
You can write an equation of a line conveniently by point-slope form. It's in the form of where
is the coordinates of a point that's on the line and
is the slope of the line.
Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose where
and
The next thing we have to do now is finding the slope, , where it's equal to
. I'll make
point 1 and
point 2.
Now let's plug that to our equation.
Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.
