Step-by-step explanation:
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.
Answer:
For a rectangle with length 3x+4 and perimeter of 10x+18, what is the width of the rectangle
3.2-3x+7
6-3x+7
-7 -7
-1= -3x divide both sides by -3
x=0.3
