What is the value of x and the perimeter of the quadrilateral. WILL AWARD BRAINLIEST IF CORRECT. ANSWERR ASAP. LINK AND TROLL ANSWERS WILL BE REPORTED!!

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

the square root of 16 is 4.

4*4 = 16

the correct answer is c) 2.
