Answer:It seems like you're asking for the value of the expression x⁴ - 3x³ + x² - 6x + 4 when x is -1.To evaluate this expression, I'll substitute x = -1 into the expression:x⁴ - 3x³ + x² - 6x + 4= (-1)⁴ - 3(-1)³ + (-1)² - 6(-1) + 4= 1 - 3(-1) + 1 + 6 + 4= 1 + 3 + 1 + 6 + 4= 15So, the value of the expression x⁴ - 3x³ + x² - 6x + 4 when x is -1 is 15.Step-by-step explanation:
Urban communities are characterized by high population density, diverse cultural amenities, and a high level of infrastructure development. Rural communities, on the other hand, are typically sparsely populated, with a focus on agriculture, natural surroundings, and a slower pace of life.Suburban communities lie between urban and rural areas, offering a blend of both urban conveniences and rural charm. These areas often feature single-family homes, schools, and shopping centers, appealing to those seeking a balance between city living and a quieter environment.Rurban areas, a relatively newer concept, combine aspects of rural and urban living. These communities are characterized by agricultural activities alongside modern amenities and infrastructure. They aim to provide residents with the benefits of both rural tranquility and urban conveniences.In summary, urban communities are highly populated with diverse amenities, rural areas focus on agriculture and nature, suburban areas offer a mix of urban and rural elements, while rurban areas blend rural living with urban amenities to create a unique community experience. Each type of community provides distinct benefits and appeals to different preferences and lifestyles.
