Answer:
Step-by-step explanation:
The given equation is √2x+1+3=0
And we have been given that x= 4
I do not agree with the solution because it does not give any real solution. It only gives possible solution. If you plug the value 4 in the original equation you will get 8 and the square root of 8 is a complex number. Thus 4 is an extraneous solution....

Answer:150 electricians,10 inspectors</h2>
Step-by-step explanation:
The solution uses unitary method.
The unitary method is a method for solving a problem by first finding the value of a single unit and finding the required value by multiplying the single unit value.
Given,
Each generator employs 
electricians.
Every 
electricians require 
inspectors.
So,every electrician require 
inspectors.
Anthony's department has 
generators.
Since each generator requires electricians, generators require 
electricians.
Since each electrician needs 
inspectors,
electricians need 
inspectors.
So,to maintain peak performance Antony's department requires electricians and 
inspectors.

The answer would be B, there are no real solutions to the secretion because the Square root of a negative number is not a real number.
The formula for the area of the rectangular is:
long * wide
So the answer is:
20*10 = 200 meters :))))
I hope this is helpful
have a nice day
