What is the value of (f +2g)(4) f(x)= (x-2)²; g(x)= x+3

18.

Step-by-step explanation:

g(x) = x + 3 so 2g(x) = 2x + 6

(f + 2g)(x) = (x - 2)^2 + 2x + 6

therefore

(f + 2)(4) = (4 - 2)^2 + 2(4) + 6

= 2^2 + 8 + 6= 18.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

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:
