Answer:
(146 + 0i)
Step-by-step explanation:
(11+5i)(11-5i)
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 11 + 5i) • ( 11 - 5i) =
(146 + 0i)

Answer: (‑(15*x))+39
Step-by-step explanation:
1y - 1/x = 1/60 = x*y =60 = x=60/y
3y - 2(60/y) = 6
3y^2-120=6y
3(y^2-40-2y) =0
y^2-40-2y=0
y = 7.4
3(7.4)-2x=6
22.2-2x = 6
2x = -16.2
x = -8.1
Answer:
