Answer:
If you have to solve for v, it's v<-1
interval notation: (- ∞, -1)
Step-by-step explanation:
20x+80
10/21
The easiest way to do this is to plot the points. I used the pythagorean theorem for this one, too. Add the side lengths to get the perimeter: 5 + 5 + 5 + 3 + √40 = 24.32455532 units or just 24 units.
