This is scene #6 in the CSI matrix algebra packet. The answer is D = 60 I just need a clear step by step on how to find D = 60. The x1, y1 are vertices on the triangle. x2, y2 is another one. It’s finding the determinant so expansion by minors would work.

Triangle inequality theorem state if each set of three numbers can be the lengths of the sides of a triangle. 1. 9, 8, 22. 2. 5,10,12. 3. 7,10,22. 4. 4,11,12. 5. 11,9,10. 6. 10,4,19. 7. 3,12,10. 8. 4,3,2. 9. 6,5,13. 10. 7,12,20. me .

What is the difference between regular convex and concave polygons

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
