Bellwork A cube has side lengths of 6 units. Write an integer expression to express the volume of the cube.. A square garden has side lengths of 10 units. Write an integer expression to express the area of the square. What if you had 2 cubes both with side lengths of 7 units, write an exponential integer for each cube and then multiply the two expressions. Explain the steps that you would take to find the product of the two volumes. С C

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

In the given figure ar(adf) =ar(cda) and ar(cdf) = ar(cdf). show that abdc and cdfe are trapeziums.

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?
