Step-by-step explanation:
You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.
So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]
=Sqrt[7(4x²)-3(2x)]
=Sqrt[28x²-6x]
We have that the total length of paper needed to cover all the tables is
From the question we are told that:
Number of tables
Length of table
Extension
Generally, the equation for the Total length tables is mathematically given by
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
In conclusion
The total length of paper needed to cover all the tables is
