Don’t really know but you have to trust me that if it’s multiple-choice it’s a or B trust me OK it helps
A(x) = x^2 - 18x + 81
A(x) = (x - 9)(x - 9)
A(x) = (x - 9)^2
the length of the side is (x - 9)

____________________
↪SURFACE AREAS AND VOLUMES
↪The VOLUME of any object is nothing but the the capacity to hold the amount of substance inside it . It defines the Amount of substance that can occupied bythe object inside it ..
↪Volume = Base Area × Height
↪thus for the Cylinder ; Volume of cylinder = Pi(R^2) × H
↪thus volume = 3.14 × R^2 × H
↪thus here given as R = 4 cm and H = 12cm
↪Volume = 3.14 × 16 × 12= 602.88 cm^3
thus
↪the Volume of the Cylinder = 602.88 cm^3

The median of the distribution is 4.
<h3>What is the median?</h3>
A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
The median is the number at the center of the data set.
Arranging the numbers in the histogram in ascending order is: 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 8, 9, 10
- Total numbers = 21
- Median = 1/2 x (n + 1)
1/2 x 22 = 11th number 4
