The area of the polygon is 624.5 square feet.

Step-by-step explanation:

The total area of the figure (), in square feet, is the sum of the areas of two triangles and a rectangle, that is:

(1)

Where:

- Area of the big triangle, in square feet.

- Area of the small triangle, in square feet.

- Area of the rectangle, in square feet.

Then, we expand the formula by using all dimensions presented in the image attached:

The area of the polygon is 624.5 square feet.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
