P = 2L + 2W P/2 = L + W 28/2 = 8 + W 14 = 8 + W 6 = W A = LW A = (8)(6) A = 48 unit2
w = 780
l x w =8 (1) l - w = 2 (2) transpose (2) l = 2+w sub into (1) w(2+w)=8 w 2 +2w - 8 = 0 (w+4)(w-2) = 0 w= -4,2 width = 2 feet, length = 2+2 = 4 feet
KEY: LENGTH=L WIDTH=W AREA=A If the length of 1 side is 8 and the area is 24, we must find the other length. Since L*W=A we know that L=8 and A=24. So, the problem looks like this: 8*W=24. So, to reverse this, 24 divided by 8 = W. 24 divided by 8 = 3, so we know that L=8 and W=3. Perimeter = W+W+L+L so 8+8+3+3= 22. I hope that you understand the process. Please post something on my page if you need further help.

That simply means that you divide w by 8. This can be written as w/8, or as (1/8)w.
8*w*w*w*w = 8w^4
1/w - 1 = - 8
8wwww = 8w^4
6 -w over 8 = -2

It's been a while, but I'll take a stab at this one. Assuming this is a rectangular shape: width = w length = w + 12 perimeter = length + length + width + width As stated above, p = 7w, so: 7w (perimeter) = (w + 12) + (w + 12) + w + w 7w = 4w + 24 (simplifying the above) -4w -4w (getting all the w's on one side) ------------------ 3w = 24 w = 8 Checking our work. Substituting 8 for w: p = 7(8) p = 56 P = (8+12) + (8 + 12) + 8 + 8 p = 20 + 20 + 8 + 8 p = 56
The formula for the perimeter of a rectangle is 2(L + W), where L is the length and W is the width. Then 16 = 2(L + W) : 8 = L + W. And L = W - 8, or W = L - 8 So, if you were dealing integers, you can choose any two numbers between 1 and 7 so that the numbers when added equal 8.
