Answer:

180 mm^2

Step-by-step explanation:

For the rectangle, you just multiply the sides together. 15x9 equals to 135. The triangle, is a little harder. For the width, you know that the width of the whole shape is 15mm. And one half of it is 9. So the other half must be 6mm. Now you have the width (6) and the length (15) of the triangle. You find the area of it which is 45mm squared. You add up both numbers to get 180.

Answer:

  the number of cookies ordered

Step-by-step explanation:

When an equation is written in the form ...

  (left variable) = (some expression involving one or more right variables)

we usually describe the "left variable" as the "dependent variable" and the "one or more right variables" as the "independent variable(s)".

Here, the equation is given as ...

  C = 3s + 30

__

This tells you C is the dependent variable, and s is the independent variable. The description also says "C is the number of cookies." Since you know that the dependent variable is the number of cookies, you can answer the question ...

  the dependent quantity is the number of cookies ordered.  (matches the first choice)
