Okay, suppose i have a rectangle, rectangle has a length and a width.
00:05
I know that the length of a rectangle is equals, is always implies equals five more than twice the width.
00:13
More than is that adds subtract multiply divide, adding five more than twice the width, twice the width, two times the width.
00:20
Okay, let's suppose the width is x.
00:21
So instead of w, i'm going to write x here in the width is the same thing as x.
00:27
The area is 817 yards squared.
00:30
So first, write out an equation that represents the relationship.
00:34
Will area equals length times width.
00:36
I know my area is 817 yards.
00:40
My length is 2x plus 5 times x.
00:44
So this is an equation that represents x.
00:47
What i could do from here is distribute x to both terms.
00:52
2x times x, 2x squared, because i add the exponent plus 5x.
00:58
And ultimately they're going to want you to solve this.
01:00
So i'm going to subtract 817 from both sides...
