Answer: The answer is
Step-by-step explanation: The given functions are
We are to find f(g(x)). To do this, first we need to evaluate g(x) and then we will apply the function f on the resulting function.
The evaluation is as follows:
Thus, the correct answer is
The side of the edge of the cube is 9. 9cm
<h3>How to determine the length</h3>
Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm
To find the edge of the face, we know that the face of the cube is a square
Formula for diagonal of a square =
Where is the side of the square
We then have,
Make 'a' the subject
a =
Simplify the surd
a = ×
a =
a =
a = 9. 9cm
Therefore, the side of the edge of the cube is 9. 9cm
