6 0

Answer:

4 more people

Step-by-step explanation:

6 people can paint several offices in 5 days

1 people can do same work in = 6 × 5 = 30 days

To complete the same job in 3 days people need = \frac{30}{3}

                                                                = 10 people

Need to hire people = 10 - 6 = 4 people

4 more people need to be hired to complete the same job in 3 days.

<h2>Answer</h2>

This answer is 18y • (y - 1)

<h2>Explanation</h2>

Step by step solution:

Equation at the end of step 1:

9 (x - y) ^2 - 9 (x^{2} - y^{2})

Equation at the end of step 2:

9 (x^2 + y^2 - 2xy) - 9 (x^2 - y^2)

Equation at the end of step 3:

9x^2 + 9y^2 - 18xy - 9x^2 + 9y^2

Equation at the end of step 4:

After performing basic +, - operation we get:

18y^2 - 18xy
