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
the answear us true im preety sure
Answer:
-75.955 kilometers
Step-by-step explanation:
multiply the speed by the time to get distance
the spacecraft is descending, so change in height will most likely be answered as a negative number
13.81 × 5.5 = 75.955
The line is parallel to the bisector of the 1st and 3rd quadrants
except it is shifted down 2 units:
Since we're considering the area below the graph (not included), the inequality is
