Hi,
Work:
Equation;
![x2 + y2 = 2cx](https://tex.z-dn.net/?f=x2%20%2B%20y2%20%3D%202cx)
Factor out 2x from expression.
![2x \times (1 + yc)](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%281%20%2B%20yc%29)
Use commutative property to reorder yc.
![2x \times (1 + cy) \: \: \: \: \: \: \: \: \: \: \: \: \: result](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%281%20%2B%20cy%29%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20result)
Hope this helps.

Answer:
Mean = 151
MAD = 9.14
Step-by-step explanation:
Given the data:
135, 160, 145, 155, 170, 150, 142
Mean = Σx / n
Mean = 1057 / 7
Mean = 151
Mean absolute DEVIATION (MAD) : Σ(x - μ) / n
[(135-151) + (160-151) + (145-151) + (155-151) + (170-151) + (150-151) + (142-151)] / 7
Mean absolute deviation = 9.14
it had to be b cuz now all quadrilateral have straight sides
