The best thing to do here is simply to list all of the actors for each number and this will let you see the GCF,
28- 1,2,4,7,14,28
42- 1,2,3,6,7,14, 21, 42
Therefore, you're correct and 14 is the GCF
Hope this helps :)
Answer:

Step-by-step explanation:
Answer:
x = 11.5
Step-by-step explanation:
Taking the logarithm base 2 will transform this to a linear equation.
2(2x+7) = 3(2x -3)
0 = 3(2x -3) -2(2x +7) . . . . subtract the left side
0 = 2x -23 . . . . . . . . . . . . . simplify
0 = x - 23/2 . . . . . . . . . . . . divide by 2
11.5 = x . . . . . . . . . . . . . . . . add 11.5
The solution is x = 23/2 = 11.5.

This value of x makes the equation become ...
4^(2·23/2 +7) = 8^(2·23/2 -3)
4^30 = 8^20 . . . . . true
