22·23 is equal to?

400 + 6
440 + 66
460 + 6

22·23 is equal to:  440 + 66

We are asked to find the expression which is equivalent to:

                                  22·23

We know that this expression could also be given by:

It could also be done as follows:

We know that:  

and

Hence, we get:

4+4+2x

or

2x+8

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
