Answer:
-16 - 30i
Step-by-step explanation:
(3-5i)^2 = (3-5i) * (3-5i)
Applying the "FOIL" method of expanding this expression through multiplication, we get:
9 - 15i - 15i - 25 (since i^2 = -1)
Simplifying this result, we get -16 - 30i
Answer: Most likely A
Step-by-step explanation:
the reason I say its A is because of the face that congruent means in line not and straight. Though in your answer it shows that they are not alined so that leaves us with complemantary and the 2 complementary answer choices are

Good luck :)

Answer:
1269 square meters
Step-by-step explanation:
The path and the plot of land form two concentric circles (they have the same center). The radius of the plot of land is 100m (half of the diameter) and the radius of the larger circle, formed by putting a 2m wide path around the plot of land, is 102m. Thus, the area of the path is 
minus 
which will be 
which is 
. Estimate 
to 3.141 and calculate, getting 1268.964... which is 1269, rounded to the nearest square meter.
Hope this helps :)
