12d -9 = 15d +9subtract 12d from each side and add 9 to each side0= 3ddivide by 3 on each side0 = d.because if zero is in the numerator or dominator it makes the faction 0.
d =25.5
2(d^2 + 6d - 8)
(d - 8)(d - 4)
12d - 9 = 15d + 9 Subtract 15 d from both sides: -3d - 9 = 9 Add 9 to both sides: -3d = 18 Divide both sides by -3: d = -6
12d is 12 dimensions
The magnification of a 4 x 12d lens is 48 times
12d -9 = 15d +9subtract 12d from each side and add 9 to each side0= 3ddivide by 3 on each side0 = d.because if zero is in the numerator or dominator it makes the faction 0.

It appears that there is missing context in your statement "J had 12D." Please provide more information or context for me to understand what you are referring to.
12d
what kinda car
d =25.5
about 200 dollars in good condition !
2(d^2 + 6d - 8)
I don't
(d - 8)(d - 4)
