Question

Solve (Sqrt9x)+4=-8. Check your solution. If there is no solution, write no solution. Show your work.

(Hint: Show your work when solving the equation AND when checking your solution.)

Answer 1

sqrt (9x + 4) = -8
squaring both side
9x + 4= 64
9x = 60
x = 60 / 9
x = 6.666 ...... :)

Answer 2

It is Sqrt'ing the 9x, then adding 4

Answer 3

ok soo solve this equation, Sqrt of 9x, Then add 4, which equals -8, Then check your answer

Answer 4

\[\sqrt{9x}+4=-8\]
\[3\sqrt{x}=-12\]
\[\sqrt{x}=-4\]
\[x=16\]

Answer 5

hhhhmmmm if I did it that way, squaring 9 would be 3+4=7 not -8, hhhhmmmm, idk :( sorry :(

Answer 18

You can check by putting the x value back into the equation giving
\[ \sqrt{9 \times16} +4=8\]
just remember when you square root it you get a a positive and a negative answer
