The answer would be 3.20000 u can round that off
Answer:
(-2,-3), (0,-3), (-1,1)
Step-by-step explanation:
When reflecting over an axis, the axis you are reflecting over stays the same while the opposite axis becomes its opposite number, like reflect (12, -9) over the y axis, the y (-9) would stay the same but the x (12) would become (-12)
Answer:
270,000,000
Step-by-step explanation:
2.7 time 10 to the 8 means 2.7*10⁸ in scientific notation
<u>To put it in standard notation </u>
Multiply 2.7 by 10⁸, which is 100,000,000
- 2.7*100,000,000 = 270,000,000
Deck=456
area of pool=legnth times width=20 times 50=1000
the area of the deck is made up of 4 rectangles and 4 squares, the rectangles' areas come in pairs
areas are
area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)
distribute
456=40w+4w^2+100w
add like terms
456=4w^2+140w
divide everybody by 4
114=w^2+35w
subtract 114 from both sides
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
w+38=0
w=-38
false since measures in real life cannot be negative
therfor width of walkway=3ft
