Answer:
A total of 360 residents left Planet X in the past 3 years.
Step-by-step explanation:
120 are the residents per year and the 3 represents the years so when you multiply them it would make how many residents that left Planet X in 3 years.
C would equal 20. because 12 times its self plus 16 times its self equals 400. then I square 400 and got 20, which equals c
Answer:
look at the picture i have sent
4(x² - 2) = 28
1. Distribute the 4
4x² - 8 = -28
2. Plug in 3 and -3
4(3)² - 8 = 28
4(-3)² - 8 = 28
3. Square 3 and -3
4(9) - 8 = 28
4(9) - 8 = 28
28 = 28
The reason both answers are the same is because whenever you put a negative number to an even power, the result becomes positive because any negative multiplied by a negative number is always positive.
28 = 28
