Area = Length*Width Information you are given: Area = 105cm^2 and Length = width + 8 therefore: 105 = (width + 8)*width 105 = width^2 + 8*width 105 = w^2 + 8w rearranging we get a quadratic: w^2 + 8w - 105 = 0 w^2 - 7w +15w - 105 = 0 w(w - 7) + 15(w - 7) = 0 (w - 7)(w + 15) = ...

Since you don't draw the structures (and it's almost impossible to do it on these boards) I can't tell you if the name is correct or not. However, there is a cis-1,2-difluoroethylene, a trans-1,2-difluoroethylene, and a 1,1-difluoroethylene. The name of 1,2-difluoroethylene ...

You want to do things that get y all by itself on the left, so first add 12 to both sides. -9 y -12 + 12 = 93 + 12 or - 9 y = 105 now divide by -9 to get y alone - 9 y / - 9 = 105 / - 9 or y = -105/9

I'm assuming the (b + 10) and the (b + 9) terms are in the numerator. (b + 10)/5 - 7 = (b + 9)/3 Multiply each side by 15: 3(b + 10) - 105 = 5(b + 9) 3(b + 10) - 5(b + 9) = 105 3b + 30 - 5b - 45 = 105 3b - 5b = 105 - 30 + 45 -2b = 120 b = -60.

I appears that you are attempting to calculate the average rate of change of the cost as the number of units changes from 100 to 105 that rate would be [C(105)-C(100)]/[105-100] which does work out to be 101.25/5
