Astudent concluded that the solution to the
equation v2x+1+3=0 is x=4.
do you agree? explain why or why not.

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

4x and 6y

im not sure though

what i would say the best answer is a. 40.5
