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.)

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

8 years agoIt is Sqrt'ing the 9x, then adding 4

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

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

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

8 years agoIts k, Eliza27 Thats good, Thank you both!!!

8 years agoThat's wrong

8 years agour welcome for trying lolz :D

8 years agoWhat Akiroso?

8 years agoH@H@ I dunno wat juss hapenn LOLZ :D :D

8 years agoYa lol Ok im off

8 years agothx 4 da medal :D

8 years agothx 4 da medal :DElmoLovesU

8 years agoYou 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
