36
Explination:
0 x anything is still zero, but I don't know if that counts.
1 (2+1) = 3
2 (4+1) = 10
3 (6+1) = 21
4 (8+1) = 36
Answer:

Step-by-step explanation:
Hello,
At the beginning the population is 240,000
After 1 year the population will be
240,000*(1+7.75%)=240,000*1.0775
After n years the population will be

So after 7 years the population will be

So rounded to the nearest whole number gives 404,699
Hope this helps

Answer:
sin X
Step-by-step explanation:
sin X =
=
= 
12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
x = 20
12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35
y = 180 - (35+35)
y = 180 - 70
y = 110
