Question

If $7x$ is $24$ more than $x$, then $x^2$ is how much more than $\sqrt{x}$?

• A. $49-\sqrt{7}$
• B. $24$
• C. $14$
• D. $2\sqrt{6}$
• E. $6$

Answer 1

The correct option is C $14$

Given that $7x$ is $24$ more than $x$.

So, we get $7x=x+24$.

$\therefore x=4$.

So, $x^2=16$ and $\sqrt{x}=2$.

Therefore, we get that $x^2$ is $(16-2)=14$ more than $\sqrt{x}$.
