I'm confused. Can someone help me out with this problem step-by-step using the P = 2L + 2W formula?
german

We can't use P = 2L + 2W because  the sides have different lengths.

P = a + b + c + d

a = x

b = 2x

c = 2x - 2

d = x + 5

P = x + 2x + (2x - 2) + (x + 5)

P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5

P = 6x + 3

if x = 4:

P = 6 · 4 + 3

P = 24 + 3

P = 27

If 2x + 5y = 10 and x = 3y + 1, what is 11x + 11y?
saul85 [17]
You have to solve the two equations by eliminating x or y 
<span>2x+5y=10 </span>
<span>x-3y=1 </span>
<span>Multiply all terms of second equation by two and subtract from first equation, thus eliminating x </span>

<span>2x+5y-2x+6y=10-2 </span>
<span>11y=8 </span>
<span>y=8/11 </span>
<span>x=3y+1=3* 8/11+1=25/11 </span>
<span>11x+11y= 11*25/11+ 11*8/11 </span>
<span>= 25+8=33</span>
