If EG=67, then EF=?<br> There is a picture below
ikadub [295]
If EG=67 we have (3x+7)+(5x-4)=67
let's simplify
67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\  \frac{64}{8}  = x \\ 8 = x
now we know x is 8 we can use this to find EF
since EF=3x+7
3(8) + 7 = 24 + 7 = 31
so we have EF is 31!

Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)

456=40w+4w^2+100w

456=4w^2+140w

114=w^2+35w

0=w^2+35w-114

find what 2 numbers multiply to get 114 and add to get 35 and factor

-3 and 38

0=(w-3)(w+38)

set each to zero

w-3=0

w=3
