<span>(3 + xz)(–3 + xz)
</span><span>(y2 – xy)(y2 + xy)
</span><span>(64y2 + x2)(–x2 + 64y2)
</span><span>
cause
</span><span>(3 + xz)(–3 + xz)
= </span><span>(xz + 3 )(xz - 3)

--------------
</span>(y^2 – xy)(y^2 + xy)
= y^4 -x^2y^2
----------
<span>(64y^2 + x^2)(–x2 + 64y^2)

The change in the price of the stock is $46.67.
<h3>How to calculate the change in price?</h3>
From the information given, the current price will be:
= Annual dividend / Required rate
= 7/0.1
= $70
The market value of the shares will be:
= 7/6%
= 7/0.06
= $116.67
Therefore, the change in the price of the stock will be:
= $116.67 - $70
= $46.67

Answer:
1, 2 and 3
Step-by-step explanation:
Let
t -----> the number of hours the job takes
C(t) -----> the total cost for the service
we have
This is the equation of a line in slope intercept form
where
The slope m is equal to 
The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)
therefore
<u><em>The statements that are true</em></u>
1 a house call fee costs $95
2 the plumber charges $125 per hour
3 the number of hours the job takes is represented by t
321 times 23 is 7,383
3,829 divided by 1,221 is (rounded to the nearest hundredth) 3.14
(the real number was: 3.13595414)
The answer answer is 42. 8
