Answer:

Step-by-step explanation:
The domain of a function is all possible values for the value of x.
The denominator in a rational function cannot equal to 0.

Subtracting 2 from both sides.

The domain of the function is all real numbers except -2.
2(21x − 7) + 4(3x + 2) = 6(2x + 9) + 3
42x - 14 + 12x + 8= 12x + 54 + 3
54x - 6= 12x + 57
54x=12x + 63
42x=63
x= 63/42
x= 3/2
Answer:
x= 0, -1
Step-by-step explanation:
<u><em>Answer: =2.23</em></u>
Step-by-step explanation:
Square root like this: √
5=2.23
You can also round up to the nearest hundredths and it's going to be stay. If the digit is 5 or more it's going to round up to the nearest tenths, hundredths, and thousandths.
Hope this helps!
