I’ll help you with your homework if after I answer your question for you can you pay me $5 for answering your question.
Answer:
x = 23; not extraneous
Step-by-step explanation:
A solution is extraneous if it does not satisfy the original equation. Extraneous solutions can sometimes be introduced in the process of solving radical and rational function equations.
<h3>Solution</h3>
Squaring both sides of the given equation, we get ...
√(3x +12) = 9
3x +12 = 81 . . . . . . square both sides
x +4 = 27 . . . . . . . divide by 3
x = 23 . . . . . . . . . . subtract 4
<h3>Check</h3>
There is only one solution, and it satisfies the equation:
√(3×23 +12) = √81 = 9
The solution x = 23 is not extraneous.

The correct answer is A. rational expression
Rational expression refers to a fraction in which the numerator and denominator are polynomials. Polynomials are variables. So therefore rational expression is the answer to the term that describes a fraction that has a variable or variables expression in its numerator and it denominator or both.
