The length of the rectangle is n-3, ok, the width is 2
the area of a rectangle is just length * width

so, if you simplify either of those, you'd end up with 2n-6.
because same/same = 1, and 1 * anything, is just anything itself.
Answer:
y=9/7x+5
Explanation:
We have the slope, and a point that is not an intercept. We can use Desmos graphing calculator to test y-intercepts.
Answer:
17.7
Step-by-step explanation:
This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.
100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540
190 +19x + 13 = 540
203 + 19x = 540
19x = 337
x = 17.7
