√(3x+4)-3=2 add 3 to both sides
√(3x+4)=5 square both sides
3x+4=25 subtract 4 from both sides
3x=21 divide both sides by 3
x=7

Divide 24 by 8: 3. Then multiply that number by 5: 15
5/8 of 24 =15
Okay, the answer for the first problem is -24x-54. The second is -12k^4-16k^3+20k^2. Finally. the third one is -24x^3. Hope you get it.
