(a) The surface area of the prism shown is 314 square meters. Write an equation that u can solve to find the value of w.

side a=wm b=8m and c=(w+4)m (on the picture)

I'm guessing u use the formula surface area=2ab+2bc+2ac??? Well if so I need all that solved into y=ax*2+bx+c so I can solve step (b) and (c) for (b) I have to Use the discriminate to determine the number of values of w in the equation from part (a). I can do that and part c. Many thanks for your help!!! And how do u put in images cuz I can take a pic and put it in?
