can someone help me solve for x, thanks!
4.8 = (1.2 + 2x/2)^2/(.30 - x/2)
i have tried to mult. 4.8 with (.30 - x/2) but doesnt get the correct numbers.
Okay, your equation is . If you go ahead and multiply boht sides by .3- x/2 as you say, you get .
You might as well go ahead and multiply both sides by 4 as well:
[tex]5.76- 9.6x= (1.2+ 2x)^2]/math]
Now multiply out that right side:.5.76- 9.6x= 1.44+ 4.8x+ 4x^2
Solve that quadratic equation for x. Don't forget to put the answers back into the origin
