So, the required width of rectangular piece of aluminium is 8 inches
Step-by-step explanation:
We are given:
Perimeter of rectangular piece of aluminium = 62 inches
Let width of rectangular piece of aluminium = w
and length of rectangular piece of aluminium = w+15
We need to find width i.e value of x
The formula for finding perimeter of rectangle is:
Now, Putting values in formula for finding Width w:
After solving we get the width of rectangular piece :w = 8
So, the required width of rectangular piece of aluminium is 8 inches
we have
This is the equation of the line in standard form
so
The graph is a straight line
we are going to proceed to verify the first two cases only
<u>case A)</u> It is a straight line joining the points ,
, and
Using a graphing tool
The three points are on the straight line
see the attached figure N
<u>case B)</u> It is a straight line joining the points ,
, and
Using a graphing tool
The three points are not in the straight line
see the attached figure N
therefore
<u>the answer is</u>
It is a straight line joining the points ,
, and
