If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
a + c - b = 3 + 2 - 5 = 5 - 5 = 0
b = sqrt32 or 4 root 2
a=-2 4b=-2 --> b=-1/2 c=8 (-2)(-1/2)(8)(3)= 24
it equals 4c
If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
a + c - b = 3 + 2 - 5 = 5 - 5 = 0
b = sqrt32 or 4 root 2
If you mean 3c = 214, then c = 68
a=-2 4b=-2 --> b=-1/2 c=8 (-2)(-1/2)(8)(3)= 24
You would do it it by oppisites. 3+2+4=9 which equals C.
it equals 4c
c+c+c=6 C=2 Because: 2+2+2=6
If: C = 2r Then: r = C/2
2
a^2+b^2=c^2 3^2+4^2=c^2 9+16=c^2 25=c^2 (take square root of both sides) c=5
2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
