Answer:
The two numbers are - 12 and - 12 .
Step-by-step explanation:
Let the two numbers be x and y then
By the question
x * y = 144
or x = 144 / y ....... I)
Again
x + y = - 24
Or 144/y + y = - 24
or, ( 144 + y²) / y = - 24
or, 144 + y² = - 24y
y² + 24y + 144 = 0
y² + ( 12 + 12 ) y + 144 =0
y² + 12y + 12y + 144 = 0
y(y + 12 ) + 12 ( y + 14) = 0
( y + 12 ) ( y + 12 ) = 0
Either
y + 12 =0
y = - 12
Now
x = 144 / - 12 = - 12
Therefore the two numbers are - 12 and - 12 .

The expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662
<h3>The expected population in 2025</h3>
The expected population of each country is calculated as:
P(n) = a *(1 + r)^n
Where:
- a represents the initial population
- r represents the growth rate
- n represents the number of years since 2000
2025 is 25 years since 2000.
This means that:
n = 25
So, we have:
<u></u>
<u>Australia</u>
P(25)= 19169000 * (1 + 0.6%)^25
P(25)= 22261221
<u>China</u>
P(25)= 1261832000* (1 + 0.6%)^25
P(25)= 1465382683
<u>Mexico</u>
P(25)= 100350000 * (1 + 0.6%)^25
P(25)= 116537821
<u>Zaire</u>
P(25)= 51965000* (1 + 0.6%)^25
P(25)= 60347662
Hence, the expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662
