Answer:

-0.25 units

Step-by-step explanation:

144x^2 - 72x + 9 = 0

common factor: 9

16x^2 - 8x + 1 = 0

(4x + 1)^2 = 0

4x +1 = 0

4x = -1

x = -0.25 units

Does anybody know this

AlexFokin [52]

Note that the measurements of the side of the squares are the same.

Area = base x height

Area = length x width

The area given is 400

Root 400 to get the length of the sides

√400 = 20

20 in. is your side measurement

hope this helps
