Rosa believes she can use a division expression to find the cost per pound of ground beef when 2/3 pound sells for $4. Which statement best explains why Rosa is correct or incorrect? Rosa is correct in using a division expression because the term “per” implies the quotient of the quantities before and after that word. Rosa is correct in using a division expression because the cost per pound should be less than $4. Rosa is incorrect in using a division expression because “cost per pound” refers to the product of the price and weight. Rosa is incorrect in using a division expression because the cost per pound must be an integer.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
