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
Small one: 18 and 1-thirds yards² Large one: 43.5 yards²
Step-by-step explanation:
Area of rectangle= base*height
Large one: base = 6, height= 7.25 (7 and 1-fourth)
Area= 43.5yards²
Small one: base = 3(2/3 or 2-thirds), height= 5
change the mixed fraction 3(2/3) to 11/3
area= 11/3 * 5 = 55/3
change to mixed fraction which = 18(1/3)
I think C. If that’s incorrect lmk
The positive number but a negative result would be :
C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish.
The positive value is she swam 10 feet up to the surface, but she is still below the surface, which would be a negative result.
