The function in vertex form is evaluated to be.
C. -31m⁴n - 8m²Step-by-step explanation:Given:(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)Required:Identify an equivalent expression for itSolution:Distributing the negative sign across the parentheses results in:9mn - 19m⁴n - 8m² - 12m⁴n - 9mnNext, we combine like terms:9mn - 9mn - 19m⁴n - 12m⁴n - 8m²This simplifies to -31m⁴n - 8m²Thus, -31m⁴n - 8m² is the equivalent expression for (9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn).

If Evelyn had not lost any dolls, she would have had a total of 9 dolls. Initially, Evelyn owned 9 dolls and lost 1/3 of them, which equals 3 dolls. As a result, after the loss, she had 6 dolls left. Consequently, had all the dolls remained with her, she would possess 9 dolls.
