A brick walkway forms the diagonal of a square playground. The walkway is 20 m long. To the nearest tenth of a meter, how long is one side of the playground?

14 meters

Step-by-step explanation:

The equation will be:

x^2 + x^2 = 20^2

Add x^2

2x^2=400

Divide both side by 2

x^2 = 400/2

x^2 = 200

Square both side

x = sqrt(200)

x = 14 meters

So each side has 14 meters

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
