3x+2(3x-3)=2
9x-6=2
9x=8
X=8/9
Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 18) / 4) + 18
C = (56.52 / 4) + 18
C = 14.13 + 18
C = 32.13 miles
Hope this helps! :)
Five names for -214 are negative 214, drop of 214, minus 214, below 214, and taking away 214.
2/6 and 4/6
(just multiplied 1/3 and 2/3 by 2)

assuming you mean SURFACE area
look at shape
fold it out or whateveryo yo like
we see that the faces are
4 triangles
4 rectangles in midddle
4 more triangles on other side
calculate areas
area of triangle=1/2bh
area of rectangle=bh
leftmost side
h=1.8
b=2
4*1/2*2*1.8=7.2 cm^2
middle recangles
base=3
height=2
aera=3*2=6
multply by 4 snce 4 recangles
6*4=24 cm^2
other triangles
b=2
h=2.71
total area=4*1/2*2*2.71=10.84cm^2
add them up
7.2cm^2+24cm^2+10.84cm^2=42.04cm^2
8. interesting question, not enought time to answer for me and partially too copmplex
