If 10 m of fencing are required to enclose a rectangular garden, what is the area, A, of the garden as a function of the length of one side? Select one: O a. A = 40- 4X O b. A = --x2+ 10x O c. A =5-X Od. A = -x2+5x Solve x2 + 8x = 4. Select one: O A. x == -4+2\\/5 and x = -4 -2V/5 O B. x = 4+ 21/5 and x = 4 - 2V/5 O C. x = -4+ 21/3 and * = -4 -2V/3 OD. x = 4+21/3 and x = 4 -21/3
