Answer: 8
Step-by-step explanation:
% means out of a hundred. So, 140% should be 140/100.
We have to multiply given (3-2i)(3+2i)
(3-2i)(3+2i)=9-6i+6i+4i^2
9+4i^2
We know that i^2=-1, so lets substitute it
9+4*(-1)=9-4=5
Answer:
Area = Length * Width
38 1/4 = L * 4 1/2
L = (38 1/4)/(4 1/2) = (153/4)/(9/2) = (153 * 2)/(4 * 9) = 17 1/2
Step-by-step explanation:
3:4 is the equivalent ratio
