Answer:
b. 9^(x-3) = 9^3
Step-by-step explanation:
Realizing that 729 = 9^3, we can rewrite the equation ...
9^(x -3) = 729
as ...
9^(x -3) = 9^3 . . . . . . matches the second selection
__
Recognizing that 9 = 3^2, a couple of other equivalent forms can be made.
(3^2)^(x -3) = (3^2)^3
3^(2x-6) = 3^6
or, taking the square root, ...
3^(x -3) = 3^3
None of these forms match any answer choices.

The solution will be found by matching exponents:
x -3 = 3
x = 6
A triangle always equals 180 degrees so to find the degree of angle c is you must find out what the other angles are . In this picture it shows that the triangle directly across from the triangle you are trying to figure out the angle for .They are identical triangles so that means that angle d is 24 degrees so you have 24 for one corner of the triangle . Angle d and c are identical also so that means angle c is also 24 degrees . So that means (if you were solving for the whole triangle) that angle c and d are both 24 degrees meaning the unknown angle or the top of the triangle would be 132 degrees. So the answer is C=24 degrees. Hope this helped atleast a little .
Step-by-step explanation:
6 problems= 8 seconds
1 problem = 4/3 seconds
16minutes= 960 seconds
960seconds÷4/3 seconds
=720
I'm not sure but I tried lol
