The area of a rectangular garden can be represented by the function
f(x) = x(2x + 5)
Find the area if the length, x, is 3 feet.

The area is length times width
width=x and length is z

if the length is 5 more than twice the width, express the area in terms of the width

so then
f(x)=xz
z=5+2x or 2x+5
f(x)=(x)(2x+5)

Now we have 11 possible options for blank number three.
13 12 11 __ __ __

Now we have 10 possible options for blank number four.
13 12 11 10 __ __

And so forth until we get:
13 12 11 10 9 8

Now we just have to multiply the numbers all together.
13 * 12 * 11 * 10 * 9 * 8
is equal to:
