**Kate**, Wednesday, February 9, 2011 at 10:18pm935*1.4 mil = P*4.5 mil (mult 935 by 1.4)

1309 mil = P*4.5 mil (divide both sides by 4.5)

290.8888888888888=P

So P = $290.89

**Jade**, Sunday, February 13, 2011 at 1:24pmtwo congruent opposite sides of a trapezoid are each 4 inches longer than the top base of the trapezoid. The top base of the trapezoid is one third as long as the bottom base of the trapezoid. If the perimeter is 56 inches, what is the length of each of the four sides of the trapezoid?

**Patrick**, Monday, February 14, 2011 at 11:04amAnswer to Jade:

The bottom of the Trapezoid =x, the top = (1/3x), the sides then = (1/3x + 4").

So the equation looks like this:

x + 1/3x + (1/3x + 4) + (1/3x +4)=56

Solve for X:

2x + 8 = 56

then x=24

Plug your # for x back into the dim. for each side and you get:

Bottom = x = 24

Top = (1/3(24)) = 8

Sides= (1/3(24))+4 = 12
