Answer:

$y^6$ , $12n^6$ , $20x^9$

Step-by-step explanation:

When you multiply like variables with each other, you add their powers together.

So...

1. $(y^2)(y)(y^3)\\y^{2+1+3} \\y^6$

2. $(3n^2)(4n^4)\\12n^{2+4}\\12n^6$

3. $(5x^4)(4x^5)\\20x^{4+5}\\20x^9$

slavikrds [6]

Answer:

<h2><u>28 eggs did not hatch.</u></h2>

Step-by-step explanation:

<h3>1) Calculate 9/15 of 70 eggs. </h3>

$\frac{9}{15}$ × 70

$= \frac{630}{15}$

= 42

<h3>2) To calculate how many eggs <u>DID NOT</u> hatch, we should subtract 42 from 70.</h3>

70 - 42 = 28

<u>28 eggs did not hatch.</u>
