Answer:

x=10.75 in

Step-by-step explanation:

A = 390 = x(3x+4)

3x²+4x-390 =0

ax²+bx+c=0

x= (-b±√b²-4ac)/2a

x= (-4±√(16+4680))/6 = (-4±2√1174)/6 = (-2±√1174)/3

We will consider only the x that gives us a positive answer because the dimensions cannot be negative.

x= (-2+√1174)/3 = 10.75456113≈ 10.75

The arrangement in order would be 22.5, 31, 41.5, 49.85, 52.9, 56.05
the mean would be $42.30 (Added all and divided by 6)
the median would be $45.68 (41.5+49.85=91.35/2= 45.675)
there would be no mode.
