The length of fourth side is: 8a-2
Step-by-step explanation:
Given
Perimeter = P = 39a-7
![Side1 = s_1 =9a\\Side2=s_2=5a+1\\Side3=s_3=17a-6\\Side4=?](https://tex.z-dn.net/?f=Side1%20%3D%20s_1%20%3D9a%5C%5CSide2%3Ds_2%3D5a%2B1%5C%5CSide3%3Ds_3%3D17a-6%5C%5CSide4%3D%3F)
The perimeter is given by:
![P = s_1+s_2+s_3+s_4\\39a-7 =9a+5a+1+17a-6+s_4\\39a-7=31a-5+s_4\\s_4=39a-31a-7+5\\s_4=8a-2](https://tex.z-dn.net/?f=P%20%3D%20s_1%2Bs_2%2Bs_3%2Bs_4%5C%5C39a-7%20%3D9a%2B5a%2B1%2B17a-6%2Bs_4%5C%5C39a-7%3D31a-5%2Bs_4%5C%5Cs_4%3D39a-31a-7%2B5%5C%5Cs_4%3D8a-2)
The length of fourth side is: 8a-2

Answer:
These points aren't a function
Step-by-step explanation:
The two points on the y-values are stacked, therefore, the function is not a function.
