Answer:
3(16 + (─40) + 4) = -60
(─10 + 18) × (─1) = -8
Step-by-step explanation:
3(16 + (─40) + 4)
PEMDAS:
3(16+(-40)+4)
3(-24+4)
3(-20)
-60
(─10 + 18) × (─1)
PEMDAS:
(-10+18) x (-1)
8 x -1
-8
These are your answers

The water consumption based on the information for three months will be 22267m³.
<h3>How to calculate the values?</h3>
The total water consumption for the three months will be:
= 7219 + 7390 + 7658
= 22267m³
In conclusion, the information simply wants you to add the values of the water given.
Therefore, the water consumption based on the information for three months will be 22267m³.

Answer:
The restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
Step-by-step explanation:
As we know that
There are two genuine reasons why domains are restricted.
We cannot divide the expression by 0 as it would be undefined then.
We cannot take the square root of a negative number, as the result will not be a defined.
Considering the expression
As we can not put x = 0 in the denominator as it would make the expression undefined.
In other words, the certain values which make the denominator equal to zero for a rational expression will be restricted values.
Hence, the restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
