A polyhedron has 6 faces and 7 vertices, how many edges does it have

Step-by-step explanation:

Euler's Formula:

We have:

Substitute these numbers into formula and solve for E:

This polyhedron  has 11 edges

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

here the number -5 is all of the following except a rational number.
