I have having a problem with this equation 3(-2-3x) = -9x-4

inn [45]

Answer:

3(-2-3x) = 9x-4

-6-9x = 9x-4

-6+6-9x = 9x-4+6

-9x = 9x+2

-9x-9x = 9x-9x+2

-18x = 2

-18x÷(-18) = 2÷(-18)

x = -(1/9)

Thank you

I need help finishing a question. I used the explanation function on the program, but it didn't specify what to do to get the fi

leva [86]

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337

Add this to 1 and we have 40.75093337

Then divide over 2pi to get a final approximate result of 6.48571248

So x = 6.48571248 is one approximate solution

In short, I computed $\frac{1+\sqrt{1+160\pi^2}}{2\pi}$ only focusing on the plus for now.

----------------------

If you were to compute $\frac{1-\sqrt{1+160\pi^2}}{2\pi}$ you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.
