Select all polynomials that are divisible by (x+1). Choose all answers that apply: 1. A(x) = x^4-3x^3-4
2. B(x) = x^4+2x+1
3. C(x) = x^3-3x^2+4x-2
4. D(x) = x^3+2x^2-5x-6

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.

Which one ? is the answer and how to find this answer

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)
