A class of second graders is learning about the properties associated with lines in regards to measurement and length. the students are learning to define geometric terms by their proper definitions. which of the following would define a line a-lines are represented by a dot and a letter
b-lines are geometric figures made up of two rays or two line segments that have the same endpoint
c- a line is a flat surface that extends infinitely in all directions and has no thickness. it is a two-dimensional infinite set of points.
d-a line is a set of points that form a straight pathway extending infinitely in opposite directions.

Suppose that one doll house uses the 1 inch scale, meaning that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. if the doll house is 108 inches wide, what is the width of the full-sized house that it's modeled after? in inches and feet.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
