The length of the rectangle is = 72 cm
The width of the rectangle is = 56 cm
Area of the rectangle is = 
=
cm²
As given, the other rectangle has the same area as this one, but its width is 21 cm.
Let the length here be = x


Hence, length is 192 cm.
We can see that as width decreases, the length increases if area is constant and when length decreases then width increases if area is constant.
So, in the new rectangle,constant of variation=k is given by,
or 
Hence, the constant of variation is 
Answer:
(-5,-1)
Step-by-step explanation:
First, draw a parallel line to the blue one that has a slope of over 1 to the right and up 1.
Second, look at the new line and see if any of the points are on the line.
All of the other point do not fall on the new line.
Answer:
2.5
Step-by-step explanation:
We know that
the equation of a line is
y-y1=m*(x-x1)
we have
y=5.8x-9-----> the slope m=5.8
if the lines are parallel
then
the slopes are the same
point <span>(8,1)
</span>y-y1=m*(x-x1)----> y-1=5.8*(x-8)
the answer is
y-1=5.8*(x-8)
2x° + 1 + x° - 6 + 59°= 360°
3x° + 54° = 360°
3x = 306°
x = 102°
2(102°) + 1°= 204° + 1° = 205°
102° - 6°= 96°
205° + 96° + 59°= 360°
