Answer:
(x - 9)(x - 9)
Step-by-step explanation:
<em>Hey there!</em>
Well to factor,
x^2-18x+81
we need to figure out what times what equal 81 and adds together to get -18.
-9*-9 = 81
-9 + -9 = -18
x*x = x^2
Factored - (x - 9)(x - 9)

Answer:
<h2>
64/27</h2>
Step-by-step explanation:
If x and y be real numbers satisfying 2/x=y/3=x/y, then any two of the equation are equated as shown;
2/x = y/3 ... 1 and;
y/3 = x/y... 2
From equation 1, 2y = 3x ... 3
and from equation 2; y² = 3x ... 4
Equating the left hand side of equation 3 and 4 since their right hand sides are equal, we will have;
2y = y²
2 = y
y = 2
Substituting y = 2 into equation 3 to get the value of x;
2y = 3x
2(2) = 3x
4 = 3x
x = 4/3
The value of x³ will be expressed as (4/3)³ = 4*4*4/3*3*3 = 64/27

Answer:
3
Step-by-step explanation:
You want the greatest of three consecutive odd integers that have a sum of 3.
<h3>Average</h3>
The average of the integers is their sum divided by their number:
average = 3/3 = 1
This is the value of the middle of the three integers, so they are ...
-1, 1, 3
The greatest of the three is 3.
