For this case we have that by definition, the volume of a parallelepiped is given by:
Where:
l: It's the long
w: It is the width
h: It's the height
From the figure we have the following data:
We must find the value of the length of the parallelepiped:
Answer:
Formula :
Base²= Hypotenuse² - Perpendicular ²
Remember the a² in formula has nothing to do with the a we have to find. :)
The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:
The equation represented on machine B is:
Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:
So, we have:
Open brackets
Collect like terms
Divide both sides by 2
Substitute 39 for x in
Hence, the output produced by both machines is 372
