Answer 2

It looks like you have a series of equations. Let's solve each of them step by step:

1. 9X - 18 = p(8.2 - 8.5)^2 First, calculate the value inside the parentheses: (8.2 - 8.5)^2 = (-0.3)^2 = 0.09

Now, rewrite the equation: 9X - 18 = p * 0.09

To isolate X, divide both sides by 9: 9X/9 - 18/9 = (p * 0.09)/9

X - 2 = 0.01p

2. x^2 - 9x + 18 = 0 To solve this quadratic equation, you can factor it: (x - 6)(x - 3) = 0

Now, set each factor equal to zero: x - 6 = 0 or x - 3 = 0

Solve for x in each equation: x = 6 or x = 3

So, there are two possible values for x: x = 6 and x = 3.

3. x^2 - 4x + 5 = 0 To solve this quadratic equation, you can again try to factor it: (x - 5)(x - 1) = 0

Now, set each factor equal to zero: x - 5 = 0 or x - 1 = 0

Solve for x in each equation: x = 5 or x = 1

So, there are two possible values for x in this equation as well: x = 5 and x = 1.

It appears you have three separate equations with various solutions.
