Polynomial equation of the second degree
m being the smallest and largest n root root of the equation x² + 11x + 10 = 0, one can conclude that the result of the expression m + 35 / n- 4 is:

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
