Answer:
1: 7/12 2:1/3 3:1/2 4:1/3 5:5/8 6:1/2 7:6/10 8:1/1 9:1/4
Step-by-step explanation:
lo saque de otro trabajo igual.
Multiply each exponent inside the parentheses by the exponent on the outside:
8^(-5 x -4) / 2^(-2 x -4)
8^20 / 2^8
The answer is C
If they proportional, it implies
(x+2)/(x-1) = 8/10
Or 10x +20 = 8x-8
Or 2x = -28 or x = -14
A and D because it is basically saying 3:36 so when you simplify it comes down to 1:12
