ABCD is a parallelogram. AB= 4z-5, BC=w+3, AD= 4w and CD= 2z+1. Find the length of the following sides: AB and BC

the answer would be  

a.

3: 1

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

i think the answer is b x = 1, y = 35/2
