The answer is A: because 3x • 4x = 12x^2; 3x • 3 and -2 • 4x make 9x-8x which is just x; and -2 • 3 is -6
Answer:
18 days
Step-by-step explanation:
Let x represent number of days.
We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall
seconds behind in x days.
We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total
seconds in x days.
Since Brady's watch is 22 seconds behind, so we will equate
by 22 to solve for x as:



Therefore, Brandy set her watch 18 days ago.
