Answer:
First option: 
Step-by-step explanation:
<h3>
The complete exercise is: "The height of a hill, h(x), in a painting can be written as a function of x, the distance from the left side of the painting. Both h(x) and x are measured in inches 
. What is the height of the hill in the painting 3 inches from the left side of the picture?</h3>
You have the following function provided in the exercise:
You know that 
represents the height of the hill (in inches) and "x" represents the distance from the left side of the painting (in inches)
Knowing that you can determine that, if the painting 3 inches from the left side of the picture, the value of "x" is the following:
Therefore, you need to find the value of when in order to solve this exercise.
So, the next step is to substitute into the function:
And finally, you must evaluate in order to find 
.
You get that this is:
Square roots and squaring are always nonlinear.

Step-by-step explanation:
1. to check the congrency normally distance formula is used. if the distances/ length are equal we say that sides are congurent.
2. if the slope of two lines are equal then both the lines are parallel. if the product of the slopes of two lines equal to one then lines will be perpendicular.
3. diagonals bisect or not can be checked by using midpoint formula.
4. equilateral triangle if the distance of each side is equal so, distance formula can be used.
