Answer is B. 2.19/Ib (just divide 4 by 8.76)
So what you need to do is add all of the veggies up. 2+1.5+1= 4.5 Then you write the ratio out. 1:4.5. This can also be written as 2/9 or .222 repeating
=(14+3i) - (-12-7i) + (6+2i) =14 + 3i +12 + 7i + 6 + 2i =32 + 12i
=3(3z)2-3 =3(9z2)-3 =27z^2-3 =3(9z^2-1) =3(3z+1)(3z-1)
