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

since both sides equal, there are infinitely many olutions.

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
