Answer:
8x+6
Step-by-step explanation:
To simplify it, the first thing you want to do is distribute the three.
So
3(x+2) = 3x+6,
So we can then add the 5x to it.
3x+6+5x
Then, Combine Like Terms
8x+6

Answer:
1,404,000 unique passwords are possible.
Step-by-step explanation:
The order in which the letters and the digits are is important(AB is a different password than BA), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
2 digits from a set of 10(there are 10 possible digits, 0-9).
3 characters from a set of 26. So
1,404,000 unique passwords are possible.
Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for . Now we can divide both sides by 3, getting. we subtract the first equation from our equation we just got, getting y= (5,-5). once we plug that in, we get , x = (-3,3)
