Answer:
[6.5,-7.25]
Step-by-step explanation:
Given the partitioning ratio as 3:1
#Find the length of the x-coordinate and multiply by the ratio:
x length=9--1=10
=>
#We subtract 2.5 from the x-max to get the point=9-2.5=6.5
#Find the length of the y-coordinate and multiply by the ratio:
x length=-9--2=-7
=>
#We subtract -1.75 from the y-max to get the point=-9--1.75=-7.25
Hence,  the coordinates that partitions the segment into a ratio of 3 to 1 is [6.5,-7.25]

(k-9)²
=(k-9)(k-9)
=k(k)-9(k)-9(k)-9(-9)
=k²-9k-9k+81
=k²-18k+81. As a result, the product of (k – 9)2 using the perfect square trinomial rule shown on the left is k²-18k+81. Hope it help!
