Answer:
65
Step-by-step explanation:
Here is the full question :
Asher owns a square plot of land. He knows that the area of the plot is between 4200 and 4300 square meters. Which of the following is a possible value of the side length of the plot of land? 45, 55, 65, 75
The formula of the area of a square is 
Given the information that the area is between 4200 and 4300 square meters, trial and error would be used to determine which of the options is correct
45^2 = 2025
55^2 = 3025
65^2 = 4225
75^2 = 5625
it can be seen that it is only 65 that is between between 4200 and 4300 square meters.

Answer:
1st
Vertex
we have
f(x)=x²-18x+88
let
y=x²-18x+88
comparing above equation with ax²+bx+c
we get
a=1
b=-18
c=88
now
vertex(x,y)=(-b/2a,f(-b/2a))
x=(18/2×1)=9
y=f(9)=9²-18×9+88=7
SO
VERTEX(X,Y)=(9,7)
=
