P2 + 4p - 12 = 0 Find the value of the discriminant. A) 2 B) 4 C) 8 D) 64

D

Step-by-step explanation:

given p² + 4p - 12 = 0 ← in standard form

with a = 1, b = 4, c = - 12, then the discriminant

Δ = b² - 4ac

 = 4² - (4 × 1 × - 12) = 16 - (- 48) = 16 + 48 = 64 → D

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:
