Discount by 12%:
$65 x 0.12 = $7.8
Retail price after discount:
so $65 - $7.8 = $57.20
Answer
$57.20
Answer:
Step-by-step explanation:
Let us assume that the eagle's elevation is 100 meters above.
We can multiply -14.2 by 0.8.
We now get -11.36.
We can add this to (-14.2*4).
We now get -11.36 + -56.8.
We can add those together to get the answer.
-11.36 + -56.8 = -68.16.
Then we can add that to 100 (since it is negative).
100 + (-68.16) = 31.84.
The eagle's elevation would be 31.84 meters if its starting position was 100 meters, meaning that the equation would be (a - 68.16).

- If the square of a number is added to 8 times the number, the result is 100. Find x.

Let's take the number as 'x'.
- Square of x = x²
- 8 times x = 8x
We are given that, 8x + x² = 100
Now, let's solve for x.

Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x²+bx=c.

Divide 8, the coefficient of the x term, by 2 to get 4. Then add the square of 4 to both sides of the equation. This step makes the left-hand side of the equation a perfect square.

Square 4.

Add 100 to 16.

Factor x²+8x+16. In general, when x²+bx+c is a perfect square, it can always be factored as
.

Take the square root of both sides of the equation.

Simplify.

Subtract 4 from both sides of the equation.

- x can be either of these values.

Answer:
Option D.
Step-by-step explanation:
The given statement is

x-4 is difference between x and 4.
|x-4| distance from x because distance can not be negative.
Inequality sign "<" means less than.
represent all values of x whose distance from 4 is less than 0.5.
Therefore, the correct option is D.
