Dahasolnce [82]
Xy = 940 

<span>and </span>

<span>Cost = 5(2x) + 5y + 10y (I chose y to be the side with brick). The cost equation simplifies to: </span>

<span>C = 10x + 15y </span>

<span>Replace y in the cost equation with 940/x: </span>

<span>C = 10x + 15(940/x) </span>

<span>C = 10x + 14100/x <---this is the equation you need to minimize. </span>

<span>C' = 10 - 14100/x^2 </span>

<span>10 - 14100/x^2 = 0 </span>

<span>14100/x^2 = 10 </span>

<span>x^2 = 14100/10 = 1410 </span>

<span>x = sqrt(1410) = 37.55 </span>

<span>y = 25.03 <---this is the length of the brick fence.</span>

Answer:

<h2><u>k = ¹¹⁄₁₅ Or 0.73333333333</u></h2>

Explanation:

<u>Find The Least Common Multiple Of 4 And 2: 4</u>

  • <u>Multiply By LCM (4)</u>

¹³⁄₄k · 4 + ½k = ¹¹⁄₄ · 4

<u>Simplify</u>

15k = 11

<u>Divide Both Sides By 15</u>

15k / 15 = 11 / 15

<h2><u>k = ¹¹⁄₁₅ Or 0.73333333333</u></h2>
