marked 15 units and four right angles. Two trapezoids labeled V R A S and B U W D. Sides B U and V R contain one tick mark. Sides B D, U W, V S, and R A each contain two tick marks. Sides A S and W D each contain three tick marks. The angles represented by vertex letters U, B, R, and V each contain two tick marks. The angles represented by vertex letters D, W, S, and A each contain one tick mark. Two rectangles labeled B M D J and K Z Y A. Sides B M and D J are each labeled twelve, and sides D M and J B are each labeled six. Side K Z and side Y A are each labeled four. Side Y Z and side K A are each labeled three. All angles in both rectangles are right angles. Two quadrilaterals labeled L X C A and P T Z Q. Sides L X and P T are labeled two. Sides A L and Q P each contain one tick mark. Sides A C and Q Z each contain two tick marks. Sides C X and Z T each contain three tick marks. Angles X and T are right angles. Angles L and P are labeled seventy-two degrees. Angles A and Q are labeled one-hundred and fifty-three degrees. Angles C and Z are labeled forty-five degrees.

</span><span>Question 3: 
A company distributes its product by train and by truck. The cost of distributing by train can be modeled as −0.06x2 + 35x − 135, and the cost of distributing by truck can be modeled as −0.03x2 + 29x − 165, where x is the number of tons of product distributed. Write a polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck. 


we have that
[</span>the cost of distributing by train]-[the cost of distributing by truck]
=[−0.06x2 + 35x − 135]-[−0.03x2 + 29x − 165]
<span>=(-0.06x2+0.03x2)+(35x-29x)+(-135+165)
