x=6 or x= -10
Answer:
x = 10
Step-by-step explanation:
3![3x(3+5x)=240\\9x+15x^{2} =240\\\\9x+\sqrt{15x^{2} } =240\\9x+15x=240\\24x=240\\x=10](https://tex.z-dn.net/?f=3x%283%2B5x%29%3D240%5C%5C9x%2B15x%5E%7B2%7D%20%3D240%5C%5C%5C%5C9x%2B%5Csqrt%7B15x%5E%7B2%7D%20%7D%20%3D240%5C%5C9x%2B15x%3D240%5C%5C24x%3D240%5C%5Cx%3D10)

Step-by-step explanation:
We write an expression:
![\frac{1}{4} (\frac{8}{3} *9)-3](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%28%5Cfrac%7B8%7D%7B3%7D%20%2A9%29-3)
Then we simplify:
![\frac{1}{4} (24)-3](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%2824%29-3)
