Ineed with the following two questions this is a desperate situation and it vance see attached images

Parallelogram with four congruent sides

Step-by-step explanation:

Rhombus: It is special type of quadrilateral whose all sides congruent and opposite sides are parallel.

Diagonals of rhombus are perpendicular bisector. Diagonals make angle 90 degree at intersection point.

Rhombus is a parallelogram with four congruent sides.

Attached image is show shape of rhombus.

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:

this is answer of 144 cubic meters
