Let the original length be x, then the new length is 6/5x
x^2 + 44 = (6/5 x)^2
x^2 + 44 = 36/25 x^2
36/25 x^2 - x^2 = 44
11/25 x^2 = 44
x^2 = (44 x 25)/11 = 100
x = 10 cm.
Therefore, original length is 10cm and new length is 1.2 x 10 = 12 cm.
Perimeter of a square = 4l
Therefore, difference in perimeter = 4(12) - 4(10) = 48 - 40 = 8 cm.

Answer:
y -2 = -2/3(x +4)
Step-by-step explanation:
There are several different forms of the equation for a line. Each is useful in its own way. Here, the line crosses the y-axis at a point between integer values, so using that intercept point could be problematical. That suggests the "point-slope" form of the equation for a line would be a better choice.
That form is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
__
The two marked points are (-4, 2) and (5, -4). All we need is the slope.
The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . . . where the given points are (x1, y1) and (x2, y2)
m = (-4 -2)/(5 -(-4)) = -6/9 = -2/3
Using the first point, the equation for the line can now be written as ...
y -2 = -2/3(x -(-4))
y -2 = -2/3(x +4)
No it is not proportional
