Step-by-step explanation:
Starting with the first one, we know that 3²=9 and 4²=16, so √10 is between 3 and 4. Similarly, √27 is a little over 5. √3 is close to 2, √2 is close to 1, and √9=3, so for simplicity, we can write this as 
The 3.something and the 3 kind of cross out, and we're left with 5.something over 2 1.somethings, which can be closer to 2 or 1, which is somewhat unclear -- therefore, our answer can be D or E, and we'll wait on this one
For the second one, we can cross out the √6s to get 
-- π is a little greater than 3, so this is E, making the first one D
For the third one, we can cross out the √3 to get (3-2)/2 = 1/2, or A as it is between 0 and 1
For the last one, note the multiplication -- cross out the √3 to get (3*2√2)/6, and we get 6√2/6=√2, or C
First some simplifying:
Then with 
and 
, we have 
and 
, so
By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.
<h3>
How long will take the egg to reach the ground?</h3>
Here we know that the initial height of the egg is 40ft, so the equation for the height will be:
The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:
This means that the egg will hit the ground after 1.58 seconds.

Step-by-step explanation:
Answer:
7x+7<u> </u><u>></u><u> </u>23-x
group like terms
7x+ x <u>></u><u> </u><u>2</u><u>3</u><u>-</u><u>7</u>
8x<u> </u><u>></u><u> </u>16
we divide both side by

8 8
so 8 cancelled out 8 living
