For the rational equation, x^2+5x+6/x+3=1 , what is a valid value of x? .

B. -1

Step-by-step explanation:

We have the equation, .

Now, factorizing the polynomial , we get that the factors of the polynomial are (x+3) and (x+2).

So, we get,

i.e.

i.e. x + 2 = 1

i.e. x = -1.

Hence, we get that the value of x is -1.

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:
