Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Step-by-step explanation:

The equation x=\sqrt{6x+7} can be solved by squaring both sides:

x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

1 = \sqrt{-1}\\ 7 = \sqrt{49}

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Two brothers are painting pictures. One of the

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Assuming you are asking what does x represent when you say "What does represent" the answer is a: the number of days it take the brothers to paint 13 pictures.

The first 2 sentences are useless and don't tell you anything (well they do but you don't need the information).

Both brothers can paint 13 pictures in x days.

So x means days, more specifically, the number of days it took for the brothers to paint 13 pictures.
