Answer:
1/4
Step-by-step explanation:
To find the roots of the expression, factor the expression by GCF.
The roots are the factors set equal to 0 and solved for x.
2x = 0
x=0
4x-1 = 0
x = 1/4
The sum is the addition of the two roots 0 + 1/4 = 1/4

Answer:
About 28,671,342 people
Step-by-step explanation:
This is compound growth problem. This goes by the formula:
Where
F is the future amount (in 3 years)
P is the present amount (28.5 million)
r is the rate of growth (0.4% = 0.4/100 = 0.004)
t is the time in years (3 years)
We first, need to find the rate of growth annually. It is given 0.4% every 2 years, so in 1 year that would be:
0.4%/2 = 0.2% = 0.002
Now, we put the information into formula and solve:
So, around 28,671,342 people will be infected in 3 years.
