For Sophia’s graduation party, several tables of the same width will be arranged end to end to form a serving table with a total

Andrew [12]

Answer:

The length is 16.1 ft and the width is 4.7 ft

Step-by-step explanation:

Let

x -----> the total length of the tables

y -----> the width of the tables

we know that

The area is equal to

$A=xy$

$A=75\ ft^{2}$

$75=xy$ -----> equation A

$x=3y+2$ -----> equation B

substitute equation B in equation A

$75=(3y+2)y$

$3y^{2} +2y-75=0$

Solve the quadratic equation by graphing

The solution is $y=4.7\ ft$

Find the value of x

$x=3(4.7)+2=16.1\ ft$

therefore

The length is 16.1 ft and the width is 4.7 ft
