Which of the following shows the polynomial below written in descending order?
5x3 - X+9x? +4 + 3x11
O A. 4 + 3x11 + 9x + 5x3 - x
B. 3x11 + 9x? + 5x3 - X+4
O C. 9x + 5x +4+3x11 - x
23
O D. 4- X+ 3x11 + 9x?+ 5x3

< i think this is the answer unless i did my math wrong

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

4would have to be the correct answer
