Answer:
<h3>80.1 x 10 <em>7</em></h3>
Step-by-step explanation:
Usually, rugs have a rectangular shape, therefore the section of the living room that Patrick wants to cover is a rectangle.
The area of a rectangle can be found by multiplying the length and the width of the rectangle:
A = l × w
Hence, the most appropriate measurements Patrick should provide are the length and the width of the section of his living room he wants to cover.
If the sum of any 2 sides is equal to or less than the third side it is Not a triangle.
So A :- we have 2+4 = 6 so its not a triangle.
also D is not a triangle because 8+3 < 12
what about B and C?
You can put the line into the equation y= MX+c
m = gradient
c = y offset
To work out m you need to divide the change in y by the change in x for two points on the graph:
6--6 = 12 (change in x)
-3--7 = 4 (change in y)
m = 4/12 = 1/3
Then to work out the c variable you need to see where the line crosses the y axis, where this happens is the c variable:
c = -5 because c crosses y at the point -5
Then place it into one equation:
y = 1/3x-5
Hope this helps! :)
