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
That depends what the value of w is.
w-8
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

James W. Lewis was born on August 8, 1946.
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
8w = 152 Dicide both sides by '8' 8w/8 = 152/8 w = 19 The answer!!!!
