Answer:
80 + 18i
Step-by-step explanation:
i² = -1
x = i + 9
x² = (i + 9)²
Applying; (a + b)² = a² + 2ab + b² concept,
x² = i² + 18i + 81
We know that i² = -1
So x² = -1 + 18i + 81
x² = 81 - 1 + 18i = 80 + 18i

Answer:
3.50$
Step-by-step explanation:
Since a nickel is 5 cents, you would do 5 x 60 which would equal 300, which is 3 dollars.
Since a penny is worth 1 cent, you would do 1 x 50 and get 50 cents, which is half a dollar.
3 + .5 = 3.50
Hope this helps!
