F(x) = 4x2 + 5x - 3 g(x) = 423 – 3.x2 +5
Find (f – g)(x).
A. (f - g)(x) = 423 – 7x2 – 52 + 8
B. (f - g)(x) = -423 + 22 + 5x + 2
C. (f - 5)(2) = 4x3 + x2 + 5x +2
D. (f – g)(2) = -423 + 722 + 5x – 8

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?
