X would be 90° ... every x is 90°
Answer:13y(x-4)
Step-by-step explanation:
13xy-52y =13y(x-4)
(n + 7)2 = n - 1
2n +14 = n - 1
2n - n +14 = n - n - 1
n + 14 -14 = -1 - 14
n = -15
(-15 + 7)2 = -15 - 1
(-8)2 = -16
-16 = -16
In rectangular form, we have the coordinates 
3, 6, 9, 12, 15
5, 10, 15
1/3 = 5/15
3/5 = 9/15
