Arectangular garden has a perimeter of 100 feet. the length of the garden is 20 feet greater than twice the width. the system of linear equations shown below represents this situation, where ℓ is the length of the garden and w is its width. find the length and width of the garden. lbrace 2ℓ + 2w = 100 ℓ − 2w = 20 the length of the garden is feet and the width is feet.

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
