The distance from lan's home to the museum is 2,640 yards. is it reasonable to say that lan's home is more than 9,000 feet away from the museum ?

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

Anyone know? is appreciated! will mark brainliest if correct!
