Question

A wooden garden tray with a base area of xy square inches is filled with soil up to a certain height. The tray contains (x2y + 10xy2 + 12xy) cubic inches of soil. The height of the tray is represented by the expression

x^2y+10xy^2+12xy/xy

Which expression below is the correct simplified form of the height of the tray?


11xy + 12

x + 10y + 12

x + 10xy2 + 12xy

x2y + 10xy2 + 12

Answer 1

Here is a picture which might help you understand what this all means..


Ultimately you are given the volume (it's a polynomial in x and y) and are asked to find the height given the length and width.

V = H * L * W

We already know L and W (they are x and y) so

V = H*XY

Solving for H we have

H = V/ (XY)

The problem is asking you to divide the polynomial x^2y+10xy^2+12xy by xy.

OR


"factor our xy" from x^2y+10xy^2+12xy

Can you factor out the xy from the polynomial x^2y+10xy^2+12xy ?
