Multiple questions: I need help on how to set up the equation. I can figure it out on my own once I know how to set it up. So please just show me how to set up the equation for these problems x 1. b Mary is a public safety engineer. She is planning the layout of a farmers' market. The market is to take place in a rectangular area that is twice as long as it is wide. On either side along the length of the rectangle, she wants to have six foot wide walkways (see the picture below). Suppose is the width of the rectangle that includes the market and the walkway (in feet). a What is the expression that represents the area allocated for the farmers' market only? Write the expression in the form ax^2+bx, and then enter the values of and . 2. Suppose the walkway is to be extended to run through the middle of the rectangle, as indicated in the picture below. The width of this extension is 6 feet. What is the expression that represents the area allocated for just the farmer's market (shown in green)? If the expression is written in the format ax^2 + bx+c, what are the values of a, b, and c? 3. Need help on this as well The farmers' market is going to be decorated using hay stacks. To compute the volume of such a hay stack, Mary uses the expression (3x2)^3 d c b a d Write the expression in its expanded form. If the expression is written in the format ax^3 + bx^2 + cx +, what are the values of , , , and ? 4. After making some adjustments to the layout of the farmers' market, Mary came up with the following expression: 2x^2-25x+50. She then factored the expression and wrote it in the form (2x+a)(x+b). What are the values of a and b? Please step by step so I can understand this
