Please help me! The i is an imaginary number<br><br> (9+4i)^2
beks73 [17]
Answer: 2500

Explanation: I turned the I into a 1 and it turned into a 41 so I added 9+41 which is 50. Then I multiplied 50 by 50 because of the ^2 which gave me 2500. I’m assuming that you can put whatever number as a replacement for the I. I’m sorry if this answer isn’t right.

bicycle costs $150. It is advertised on sale for 32% off. What is the cost savings? Solve using two different methods.
alina1380 [7]
The savings is the amount taken off or 32% of 150

32% of 150 is 0.32 times 150=48

savings is $48


or you can do
150/100=x/32
cross multiply to get
x=48


so savings is $48
