Area = 6×5 + 12×2 = 39+24 = 63
Answer:
5x-4y+4
Step-by-step explanation:
3x-4y-2+2x+6
Gathers like terms together:
3x+2x= 5x
-4y= -4y
-2+6= 4
Put it together:
5x-4y+4
Based on the information the number of people that will there after 20 years is: d.) 2.97 million.
Using this formula
P(t) = Population ×(1+ rate)^t
Where:
Population=2 million
rate=2%
time=20 years
Let plug in the formula
P(t) = 2×(1+.02)^20
P(t) = 2×(1.02)^20
P(t) = 2×1.485947
P(t) = 2.97 million
Inconclusion the number of people that will there after 20 years is: d.) 2.97 million.
