When you say congruent the figures must be the same, not just the segments
when you say the segments have equal legnth, only the segments are compared
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
This would be an exponential graph and non of the answers are exponential. but the graph would be f(x)=3^x

-x=-y-10 = x=y+10
x is 10 bigger than y
x+y=12
