Hey yall, who wants a quick 20?

aliya0001 [1]

Answer:

1) 8x

2) 12x - 3y

Step-by-step explanation:

1) Both of them have a like term, so you can subtract them across

2) 10x + 2x = 12x, have a like term so you can add them across and 3y is the outlier so that stays alone.

Hope this helps!

Michael is 3 times as old as Brandon. 18 years ago, Michael was 9 times as old as Brandon.

Zigmanuir [339]

I hope this helps you

Brandon x

Michael 3x

18 years ago

Brandon x-18

Michael 3x-18

9 (x-18)=3x-18

9x-9.18=3x-18

9x-3x=9.18-18

6x=8.18

x=8.3

x= 24

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]

$\bf \textit{the area of either pen is 2744, thus}\\\\
A=xy\implies 2744=xy\implies \cfrac{2744}{x}=y$

$\bf \begin{array}{llll}
\textit{perimeter of the garden pen}\\\\
P=2(x+y)\\\\
P=2\left( x+ \cfrac{2744}{x}\right)\\\\
P=2x+\cfrac{5488}{x}\\
----------\\

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

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

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
