1. which of the following lines of best fit represent the data if x is the number of days since the plant appeared and y is the height of the plant? a. y = –3.5x + 0.7 b. y = –0.7x + 3.5 c. y = 0.7x + 3.5 d. y = 3.5x + 0.7 2. explain why your choice of equations best fits the data. explain what the slope and y-intercept of the line of best fit mean about the bamboo plants. part c use the line of best fit chosen in part b to predict the height of a bamboo plant 40 days after appearing above the soil. show your work.

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
