The length of a ping pong table is 3 ft more than twice the width. the area of a ping pong table is 90 ft. what are the dimensions of a ping pong table?

6ft by 15 ft

Explanation:

Width = x

Length = 2x + 3

Area = 90 ft²

x(2x + 3) = 90

2x² +3x - 90 = 0

(x - 6) (2x + 15) = 0

x = 6 or x = -15/2

x = 6 ft

2x + 3 = 2 x 6 + 3 = 15 ft

a negative exponent is translated as follows:

so, we have

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
