2-63. Use your unit of measure to make a rectangle that has dimensions units by units.

What is the area of your rectangle? (That is, how many unit squares are there in your rectangle?)

When you answered part (a), did you count the squares? Did your team use a shortcut? If so, why does the shortcut work?

Compare your rectangle to rectangles that other teams made. What is the same about the rectangles and what is different?

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
