Answer:

W = 27 L = 9.

Step-by-step explanation:

Do 72 / 8 and NOT 72/4. The reason why its not 72/4 is because its talking about the perimeter. We are finding the length so we get 9 for the length. The width is 3 times the length so the width is 27.

$x^{2} +10x+30$
I always start by moving the last term to the other side
$x^{2} +10x=-30$
To complete the square you take term 'b' , divide it by 2 then square it
$( \frac{10}{2} )^2$ = 25
We have to add 25 to what we have and what you do to one side you have to do to the other
$x^{2} +10x+25=-30+25$
$x^{2} +10x+25=-5$
Now we factor what is on the left side of the equation
$(x+5)^2=-5$
The last step is to move our right side of the equation back over
$(x+5)^2+5$ - which is your answer :)))
