Jason has a piece of wire that is 63.9 inches long. He cuts the wire into 3 equal places. Estimate the length of one piece of wire. Round down your answer to the nearest integer.

21.3

Step-by-step explanation:

63.9 divided by 3 equal pieces is 21.3!

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
