If C=n^{2}+9n-8C=n 2 +9n−8 and D=3n-4,D=3n−4, find an expression that equals 2C+3D2C+3D in standard form.

the closest answer i got was 75 divided by 9 = 8.3

the formula for converting absorbance to transmittance goes as:

a = log (1/t)  a = 2 - log(%t)  10^a = 1/t  t = 10^-a  %t = 100(10^-a)

so at the given value of a,   a = 1.5

%t = 100(10^-1.5)

%t = 3.16%
