Step-by-step explanation:
Given the height of <em>6 </em>DVD cases, you can know the height of a <em>single</em> DVD case, by dividing the total height, in the number of cases ( for this problem).
Now, knowing the height of a <em>single</em> DVD case (), you can think the expression in this way: <em>If I already know the height of a single case, the height of any number of cases will be the result of multiplying the height of the case by the number of cases I want to stack.</em>
As the problem states, x is the number of cases in the stack, so, multiply the height of a single case for the number of cases (x).
This will result in the expression:
To know the height of a stack of 13 cases, just replace x=13 in the equation you just figured: , but don't forget the unit is mm, so the final result is <u>247 </u><u><em>mm.</em></u>

<h2>4x⁴yz - 16y³z = 4yz(x² - 2y)(x² + 2y)</h2>Step-by-step explanation:
The complete question in the attached figure
we have that
for c=5 and n=20------------> n*c=20*5=100
for c=2.5 and n=40------------> n*c=40*2.5=100
for c=2 and n=50------------> n*c=50*2=100
for c=1.25 and n=80------------> n*c=80*1.25=100
therefore
<span>the function that models the data is n*c=100
</span>
the answer is nc=100
