Hello,
answer f: conjugate
if all coefficients are real and a+ib a zero, its conjgate a-ib is also a zero.
Answer:
240
Step-by-step explanation:
Gain=25%
Gain=selling price - cost price
Gain = ((selling price - cost price )× 100)/ cost price
25c=(4800-c)100
25c=480000-100c
125c=480000
cost price = 3840
second statement
The selling price was 4080
Cost price 3840
therefore
Gain=selling price - cost price
Gain = 4080-3840
=240
