(a) find the rational zeros and then the other zeros of the polynomial function f(x)=x^3-91x+90: that is solve f(x)=0. (b) factor f(x) into linear factors. explain how you got the integer factors

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

answer is c

step-by-step explanation:

81/12=324/x

x=48

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
