7z+56

Step-by-step explanation:

You have to do the distributive property. So you would multiply every term inside of the parenthesis with the number that is outside of it. So you would get 7z+56

answer:

24pi or letter c

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
