Write the perimeter of the triangle as a simplified polynomial. Then factor the polynomial.

The perimeter of the triangle is _.

40 x is the answer

Step-by-step explanation:

So, A= 2x^2+1

= 3x^2

= 6x

B= x^2+4x

= 5x^2

= 10x

C= 18x+6

= 24x

now the perimeter of ️ABC

= 6x + 10x + 24x

= 40x

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:
