This question is solved applying the formula of the area of the rectangle, and finding it's width. To do this, we solve a quadratic equation, and we get that the cardboard has a width of 1.5 feet.
Area of a rectangle:
The area of rectangle of length l and width w is given by:
w(2w + 3) = 9
From this, we get that:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
In this question:
Thus a quadratic equation with
Then
Width is a positive measure, thus, the width of the cardboard is of 1.5 feet.

Answer:
1=corresponding
2=straight line angles
3=vertically opposite angles
4=co-interior
5=corresponding
Step-by-step explanation:
there are many types of angles:
1. <u>corresponding</u>
- same side of transversal
- angles are equal
- include:
ei, fj, gk, hl
2.<u>alternating</u>
- inside parallel lines
- opposite sides of transversal
- angles are equal
- include:
gj, hi
3.<u>co-interior</u>
- same side of transversal
- add up to 180 degrees
- inside the parallel lines
-include:
gi, hj
4.<u>vertically opposite</u>
-opposite sides of the intersection
-do NOT lie on a straight line
-opposite angles are equal
- include:
eh, fg, jk, il
5.<u>straight line angles</u>
-lie on a straight line
- add up to 180 degrees
- also called supplementary angles
-include:
ef, fh, hg, eg, ij, jl, lk, ik

where left side is the year (x) and right side is the value (y)
The smallest value of y is = 2.13; biggest value is = 4.259 (RANGE)
Domain is (2003 to 2015)
It seems that the equation will not be linear because as the year increases, the value of y is unstable.
The answer is C. "he said, his eyes narrowing" is not something someone said. have you no shame sir is what was said, therefore it should be is quotation marks.
