Answer:
4x + 4y + 12
Step-by-step explanation:
x + 3y − y + 3x + 2(2 + 4 + y)
Apply Distributive Property:
2(2 + 4 + y)
2*2=4
2*4=8
2*y = 2y
x + 3y − y + 3x + 4 + 8 + 2y
Combine Like Terms:
x + 3x +2y +3y - y + 4 + 8
4x + 4y + 12

Answer:
6500
Step-by-step explanation:
In 24 hours, there are 12 times 2 hours, so the bacteria count will increase by 500 twelve times. That is, the increase after 24 hours will be ...
12 × 500 = 6000 . . . bacteria
Since the starting number was 500, the total will be ...
500 + 6000 = 6500 . . . . bacteria after 24 hours
_____
If you like, you can compute the rate of change as 500 bacteria / (2 hours) = 250 bacteria/hour. Then the equation for the number is ...
bacteria = 500 + 250h . . . . . where h is the number of hours.
Filling in h=24, we get
bacteria = 500 + 250(24) = 500 +6000 = 6500 . . . . after 24 hours
