The length of a rectangular suitcase is 7 inches longer than the width. the area of the suitcase is 144 squared inches.

A = LW
A = 144
L = W + 7

144 = W(W + 7)
144 = W^2 + 7W
W^2 + 7W - 144 = 0
(W - 9)(W + 16) = 0

W - 9 = 0
W = 9

W + 16 = 0
W = -16this is an extraneous solution and will not work

So W = 9

L = W + 7
L = 9 + 7
L = 16

so ur dimensions are : Length = 16 in. and Width = 9 inand area = (9 * 16) = 144 in^2

9.

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

you will get 9.

if you divide 9 by 6 you will get 54.
