Answer:

Third Choice:

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Step-by-step explanation:

One line has

x + \dfrac{b}{2a} = \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

The next line's reason is that b/2a was subtracted from both sides.

The missing line is:

x = -\dfrac{b}{2a} \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

Then it simplifies to

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Solve for the value of w
S_A_V [24]

Answer:

w=63

Step-by-step explanation:

the equation to solve this is : (w-8)+(2x-1)=180

combine the first side of the equation so you get 3w-9

then add 9 on both sides

divide 3 by 189 which gets you 63.

plug 63 into the equation to double check

hope this helps! :))
