lutik1710 [3]

Answer:


Step-by-step explanation:

1) (3 + 2i) - (1 - 6i)

  3 + 2i - 1 + 6i

  2 + 8i

2) 4i + 3 - 6 + i - 1

   5i - 3 - 1

   5i - 4

3) 5i ( 3 - 2i )

   15i - 10i^2

   15i - 10 ( -1 )

   15i + 10

4) ( 5 + 3i ) ( 2 - 3i )

   10 - 15i + 6i - 9i^2

   10 - 9i - 9i^2

   10 - 9i - 9 ( -1 )

   10 - 9i + 9

  - 9i + 19

5) ( 2 + i ) ( 2 - i )

    4  - 2i + 2i - i^2

    4 - i^2

    4 - (-1)

    5

I hope this helps!

uranmaximum [27]

Jasmine's rate is 1/10 alleys per hour

Together their rate is 1/4.44 alleys per hour.

Joe's rate must be

1/4.44 - 1/10 = 139/1110  alleys per hour

It would take Joe

1110/139 ≈ 7.99 hours to do an alley alone.

Let's call it 8 hours.
