Answer:
xy
Step-by-step explanation:
x + y = xy because of the addition sign
Armans age : x
Aregs age: y
X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.
So therefore y = 3. So Areg is 3 years old.
Since we know that y = 3
X = 5(3)
X = 15
So therefore Arman is 15 years and Areg is 3 years.
Hello,
(x-(-1+4i))(x-(-1-4i))=((x+1)-4i)((x+1+4i)
=((x+1)²+16
=x²+2x+17
