Let the length be l, the width be w, and the area be A. The equation for the area of a rectangle is A = l*w; we know A = 77, so we need to get l in terms of w so we only have one variable to solve for. We're given l = 2w-3, so we can substitute back in: A=77=(2w-3)*w 77=2w^2-3w 0=2w^2-3w-77 0=(2w+11)*(w-7) so w=-5.5 or w=7. Since we can't have a negative width, w=7 inches. Plugging back in to our equation for l and w: l=2w-3=2(7)-3=14-3=11, so the length is 11 inches.
Area = LxW Using the figures you have 56 = L x 7 L = 56/7 L = 8

L = 2W - 3 so W x (2W - 3) = 35, ie 2W^2 - 3W - 35 = 0 This factorises as (2W + 7)(w - 5) so the positive value for W is 5 in, making L = 7 in.

Electrons with l equals 3 are in the f orbital. The f orbital has a complex shape with 7 suborbitals, each of which can hold up to 2 electrons.
Fill the 7 L. Pour from the 7 L into the 3 L and empty the 3 L. Pour from the 7 L into the 3 L again and empty the 3 L again. Pour from the 7 L into the 3 L again and leave it. Fill the 7 L again. Use it to top up the 3 L. What you have left in the 7 L is 5 L.
3 kl = 3,000 L
L = w + 3L W = 28(w + 3) W = 28w2 + 3w = 28w2 + 3w - 28 = 0(w + 7) (w - 4) = 0w = -7 and W = 4L = 7
l or L is the unit symbol for litres. Therefore 3 L is equal to 3 litres.
41.2L equals 41200cm^3
L = 14 and W = 2 would give an area (A) of 28, or 7 (L) x 4 (W) = 28 (A)

Surface Area = 2*(L*W + W*H + H*L) = 2*(7*5 + 5*2 + 2*7) = 2*(35+10+14) = 2*59 = 118 square units.
