Which is the base shape of this prism?

Triangle

Step-by-step explanation:

In a prism, the base are the two congruent polygons that are parallel to each other. Other faces are often rectangle or squares.

In the given diagram prism, two triangles are parallel to each other.

other three sides are rectangles.

Congruent parallel sides are the triangles.

So, base of the prism is a triangle

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:
