15 because 228-3 is 225 and the square root of 225 is 15
Answer:
Explained below.
Step-by-step explanation:
First of all, an integer is a whole number that can be either positive, negative or zero.
Now, a drop in temperature signifies a reduction in the temperature.
This means that if for example, the current temperature is 50 °C, a drop in temperature of 10°C would mean that the current temperature would be gotten by subtracting 10 from 50.
Now,current temperature after drop would be;
T = 50 - 10
To prove that it is gotten by adding a negative integer:
This can also be written as;
T = 50 + (-10)
Because from mathematical multiplication signs, minus multiplied by plus gives minus.
Since, T = 50 + (-10), it means that a negative integer of minus 10 has been added to the initial temperature to get the new decreased temperature.
