Answer: 94
Step-by-step explanation:
7(6)-4(2)+6(5)2=
42-8+60= 94
To find the answer, you just plug 2x in place of x (even though 2x already has an x). It would look something like this: f(2x)= (2x)^3 = 2x*2x*2x= 8x^3
I think it best to actually do the problem to determine the correct answer.
Clearing out the fractions, I found that
x(x-2) - (x -1) = 2x -5. This results in x=2 and x=3.
However, 2 is not a solution (but is an extraneous solution), because substituting 2 for x in the 2nd term results in div. by zero.
Thus, only the second answer is correct.
OK so if they ring at 6AM together then they would ring like this from now on:

Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
