1 answer:
Answer: Find the surface area with the formula
Step-by-step explanation:
<u><em> Since you did not provide the figure, I will give you a general explanation about how to solve this exercise.</em></u>
By definition, the surface area of a rectangular prism can be calculated with the formula shown below:
Where "SA" is the surface area of the rectangular prism, "w" is the width of the rectangular prism, "l" is the length and "h" is the height of the rectangular prism.
Therefore, if you know the length, the width and the height of the rectangular prism, you can follow these steps in order to calculate how much glass was used to make the tank. The procedure is:
Step 1: You must substitute the values of "l", "w" and "h" into the formula.
Step 2: Finally, you must evaluate in order to get the surface area of the rectangular prism (This value is the amount of square inches that was used to make the tank).

<h2>Explanation:</h2>
See the figure below for a better understanding of the problem. Since we have a 45-45-90 triangle, this is an isosceles triangle, so both the adjacent and opposite sides measure the same value, say, x. Then the hypotenuse would be:
Then. the ratio of the length of the hypotenuse to the length of a side is:
Answer: Choice C
We have an x axis reflection
The x coordinate stays the same while the y coordinate flips from positive to negative, or vice versa.
For example, point L is located at (-4,2) and it moves to L ' (-4, -2). The other points follow this same pattern.
