Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32
x = - 13
Answer:

Step-by-step explanation:
The expression (2 square root sign 27) - (3 square root sign 32) is
.
To simplify, simplify inside the radicals by removing perfect square factors.


The expression becomes
.
This cannot be simplified anymore because whats under the radical is not the same.
