Let f(x) and g(x) be polynomials as shown below. Which of the following is true about f(x) and g(x)?
f(x) and g(x) are closed under addition because when added, the result will not be a polynomial.
f(x) and g(x) are not closed under addition because when added, the result will be a polynomial.
f(x) and g(x) are not closed under addition because when added, the result will not be a polynomial.
f(x) and g(x) are closed under addition because when added, the result will be a polynomial.

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:

explanation:

remove parenthesis:

=

apply rule

=

multiply fractions:

=

=

divide:

=

mordancy.

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
