I think it would be 29 students in the larger class
Balance after 6 months would be 900*(900+2%). You just need to evaluate it then you will get the answer. btw 2% comes from 4% because it's half of the year.
2 km... Since 1.8 is 2(.9), you do the same for the base of the smaller triangle (just multiply by two)
Answer:
The answer is option 1.
Step-by-step explanation:
In order to simplify the expressions, you have to collect like terms :
3a² + 9ab + 5 - 4a² - 4ab + 3
= (3a² - 4a²) + (9ab - 4ab) + (5 + 3)
= -a² + 5ab + 8
You basically need to set up a porporion:
1.6/2.4 = x/7.2
x=4.8
