Answer:
x² - 8x + 20
= x²- 2*4*x + 16 + 4
= x²- 2*4*x + 4² + 4
= (x - 4)² + 4
= (x - a)² + a, with a = 4
Hope this helps!
Step-by-step explanation:
There are other factors than Roberto coming that could have affected the outcome of the game. For example, maybe the night games were against better teams to generate better ratings in prime time. Moreover, maybe the Angels do better at home due to home-field advantage. There are many factors such as these that could explain why Roberto witnessed such a high win rate at the games he went to, so it cannot be concluded that Roberto's attendance caused the Angels to win.
In order to find the value of N the below mentioned steps must be followed to make the answer more accurate.
<h3>What is the procedure to find the value of N?</h3>
To find N, you must first determine the overall population size from which a sample is collected. N represents the population's overall size, or the number of people.
For example, if you are conducting a research of voter opinions in a certain state, the value of N would be the entire number of registered voters in that state. The figure of N would be the total number of people who have received treatment with the medicine if you were researching the efficacy of a novel drug.
To calculate the size of the sample required to adequately reflect the population, statistical computations frequently employ the value of N.

An equation that can be used to determine the value of x is x² + 5x - 36 = 0.
To answer the question, we need to know what equations are
<h3>What is an equation?</h3>
An equation is an expression which shows the relationship between two variables.
Given that the x represents the length of side of the square picture and the rectangular sheet poster leaving a border around the picture of 2 inches on the bottom and 1 inch on each remaining sides.
Then,
- The width of the rectangular poster is W = x + 2 + 1 = x + 3.
- The length of the rectangular poster is L = x + 1 + 1 = x + 2
So, the area of the rectangular sheet poster is A = LW
= (x + 2)(x + 3)
Since the rectangular sheet poster has an area of 42 square inches, A = 42 in².
So, (x + 2)(x + 3) = 42
x² + 3x + 2x + 6 = 42
x² + 5x + 6 - 42 = 0
x² + 5x - 36 = 0
So, an equation that can be used to determine the value of x is x² + 5x - 36 = 0.
