Answer:

3x= 2(n-1)

Step-by-step explanation:

"Three times a number" is shown as 3x, "is' refers to an equals sign, "two times" refers to 2 multiplied by "that number" or x, "and one," which is 1. Hope this helps!

Bob wants to create two pens, as shown in the figure. One pen is for a garden and it needs a heavy duty fence to keep out the cr
sattari [20]
\bf \textit{the area of either pen is 2744, thus}\\\\&#10;A=xy\implies 2744=xy\implies \cfrac{2744}{x}=y

\bf \begin{array}{llll}&#10;\textit{perimeter of the garden pen}\\\\&#10;P=2(x+y)\\\\&#10;P=2\left( x+ \cfrac{2744}{x}\right)\\\\&#10;P=2x+\cfrac{5488}{x}\\&#10;----------\\&#10;&#10;\textit{cost of it}\\\\&#10;C=15\left( 2x+\cfrac{5488}{x} \right)\\\\&#10;C=30x+\cfrac{82320}{x}&#10;\end{array}\qquad &#10;\begin{array}{llll}&#10;\textit{perimeter of the dog pen}\\\\&#10;P=2x+y\\\\&#10;P=2x+\cfrac{2744}{x}\\&#10;----------\\&#10;\textit{cost of it}\\\\&#10;C=5\left( 2x+\cfrac{2744}{x} \right)\\\\&#10;C=10x+\cfrac{27440}{x}&#10;\end{array}

notice... the dog's pen perimeter, does not include the side that's bordering the garden's, since that side will use the heavy duty fence, instead of the light one

so, the sum of both of those costs, will be the C(x)

\bf C(x)=\left( 30x+\cfrac{82320}{x} \right)+\left( 10x+\cfrac{27440}{x} \right)&#10;\\\\\\&#10;C(x)=40x+\cfrac{109760}{x}

so, just take the derivative of it, and set it to 0 to find the extremas, and do a first-derivative test for any minimum
