mr. Lee's classroom has 966 markers. his 28 students need to share them equally so everyone can work on an art project how many
Flauer [41]
For this question, you would need to divide 966 by 28, which gives us 35.6. However, we cannot have 3/5ths of a marker, so to be fair to all the kids, they would each get 35 markers. Hope this helps

Which of the following is the difference of two squares?
Sedaia [141]

The difference of two squares expression is (d) 25a^2-36b^6

<h3>How to determine the difference of two squares?</h3>

The difference of two squares is represented as:

x^2 - y^2

Where x and y are perfect square expressions.

From the list of options, we have:

25a^2-36b^6

The terms of the above expression are perfect squares

i.e.

25a^2 = (5a)^2

36b^6 = (6b^3)^2

Hence, the difference of two squares expression is (d) 25a^2-36b^6
