First find the difference of the numerator. to do this multiply 1/x by 2 and 1/2 by x. you should get (2-x)/2x. now moving on to the whole fraction. then multiply the (2-x)/2x by 2x and the (x-2) by 2x. you should get (2-x)/(2x)(x-2). now factor out a negative from the (x-2) at the denominator to get -(2-x). so now you can cancel the (2-x) from the numerator and denominator! the answer will be 1/-2x! :)

A shelf will covered with veneer on all 6 sides. The shelf is 48 inches long, 12 inches wide and 1 inch thick. What is the surfa

So. hmmmm notice the first picture, that's a rectangular prism

is really just 6 rectangles stacked up to each other at the edges

now, notice the second picture, is a prism/shelf with a length of 48, width of 12 and height of 1

so, your shelf is really just 6 rectangles stacked up to each other at the edges

you have 2 rectangles of 48x1 on the sides
2 rectangles of 12x1 for the front and back
and 2 rectangles of 12x48, for the top and bottom

get the area of each of those rectangles, add them up, and that's the surface area of the shelf
