you add the l+l and the w+w so it look like this l+l+w+w+
Write out the equation: 16 = 4w + 2w - 2 Collect like terms (terms without w and terms with w): 16 = 6w - 2 Put all the terms without w on the same side (add 2 to both sides): 16 + 2 = 6w - 2 + 2 18 = 6w Get rid of the coefficient (divide by 6): 18 / 6 = 6w / 6 3 = w
When you divide 2w by w, you are essentially dividing 2 multiplied by w by w. This simplifies to 2 because one of the w's in the numerator cancels out with the w in the denominator. Therefore, the result of 2w divided by w is 2.
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
