weell the two digits have to be either 6 and 2, or 4 and 3, since those are the only two single digit pairs that make 12. and 6 +2 = 8, so its either 26 or 62. given the domain, the answer is 62.

It's 62.
First, if the product of the digits is 12, the digits have to be either 2,3, 4 or 6. Then I just found out that 6+2=8 and that 62 is between 30 and 90...

It's 62. Because 6 + 2 is 8 and when you find the product you multiply so 6 x 2 is 12. There you go

the number is 62.
use algebra. let the numbers be x and y.
x + y= 8, therefore y=8 - x
xy= 12
hence, x^2 - 8x + 12=0
(x-6)(x-2)=0
x is 6 or 2.
the number can only be either 26 or 62.
hence in the given range, it is 62.
hope this helps! :)
