Answer:

<em>Hello There I think the Correct answer is 3</em>

<h2> Explanation</h2>

Because it shows that 9 x 3 = 27 and 3 x 9 = 27 Sooo...I think it 3.

20×+4=4(5x+1) how many solution are in this equation
Tomtit [17]

Simplify both sides of the equation

(20)(4)= 4(5x+1)

Simplify

80 = 20x+4

Flip the equation

20x+4 = 80

Subtract 4 from both sides

20x+4-4 = 80-4

20x = 76

Divide both sides by 20

20x/20 = 76/20

x= 3.8


There is one solution in this equation

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

Step-by-step explanation:

<u>Step 1: Define</u>

Point (200, 14)

Point (225, 16)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
