If the width is 12 and the length is 18, the perimeter of the rectangle is 12 + 12 + 18 + 18, or 60. So yes the perimeter can be 60.
The change of the cost changes when the pounds of ham changes. When the pounds of ham is 0, it costs 0 dollars. When the pounds of ham is 3, it costs 12 dollars. The cost changes consistently with the pounds of ham. They change together. Every time the pounds of ham goes up by 3, the cost goes up by 12.
<h3>
Answer: 2/3</h3>
============================================================
Use the slope formula to get that answer
m = (y2-y1)/(x2-x1)
m = (5-1)/(9-3)
m = 4/6
m = 2/3
We have a rise of 2 and a run of 3.
In other words, we move up 2 and over to the right 3.
