Answer: x=9

Explanation: begin by substituting or replacing “y” with 4x since y=4x. This should give you the new equation of 4x=8x-36. Then subtract 8x from both sides so that it will cancel out 8x and leave you with 4x-8x=-36. Then combined like terms to then give you -4x=-36. Lastly, divide each side by -4 which will give you the answer of x=9 because when you divide -4 by -36, two negatives cancel each other out and leave you with a positive outcome.

For this question it is the difference of two perfect squares. This means your final answer will be (2x - 5)(2x + 5). This answer is not listed so it would be none of the above.

After review, B technically works because it is the difference of two perfect squares. This allows you to take the square root of each term while ignoring the sign and then place that back in with the original sign.

7:45 -1 hour=6:45

The concert started at 6:45


7:45+2 hours=9:45

The concert will be over at 9:45

The time outside the theater is

5:30a.m. or 5:30p.m.

It's most likely 5:30p.m. as 5:30a.m. is really early in the morning.
