Answer: Option C.
Step-by-step explanation:
The surface area of the right triangular will be the sum of all its faces.
You can observe in the figure that the faces of the right triangular prism are: Two equal right triangles and three different rectangles.
The formula for calculate the area of a triangle is:
Where "b" is the base and "h" is the height.
The formula for calculate the area of a rectangle is:
Where "l" is the length and "w" is the width.
Then, the surface area of the right triangular prism is:

Answer:
Step-by-step explanation:
To find the equation from a graphed function, you can substitute points into each equation to find the original:
A point on the graph is (2, 4). Substituting this into each equation, we get:
, which claims that 4 is equal to 30, which is incorrect.
, which claims that 4 is equal to 3/2, which is incorrect.
, which claims that 4 is equal to 4, which is correct.
We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:
, which claims that 5 is equal to 5, which is correct.
