Write the polynomial function of least degree with integral coefficients that has the given zeros.
1, 2, 4
A) f(x)= x3 – 13x² + 14x – 8
B) f(x)= x? – 7x² + 14x – 11
C) F(x)= x? – 7x² + 14x – 8
D) f(x)= x3 – 7x² + 22x - 8

the mean and mad

step-by-step explanation:

just keep asking questions until you have a better understanding.

step-by-step explanation:

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.
