5.4- Seguindo os mesmos procedimentos do item anterior, considere um quadrado de lado X, e outro quadrado de lado Y, co x>y e y>0, encontre a diferença ente as á´reas desses dois quadrados e explique como você resolveu a questão.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

answer: idk wbu

step-by-step explanation: umm..

i need more details

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
