Please answer 2 and 3 !!
Usimov [2.4K]

(2) So we know Ethan uses 1/4 cup of milk for his cake. And if he needs to make 3 times the amount of 1 cake, he'll make 3 cakes today. So we multiply the amount of cakes (3) by the amount of milk needed (1/4)

3 * 1/4 = 3/4

Ethan will need 3/4 cups of milk.

(3) We know Isabella need's 2/5 of a gallon of the food to make 1 gallon.

She want's to make 5 gallons, so like the other problem, we multiply the amount of gallons (5) by the amount of food needed (2/5):

5 * 2/5 = 10/5 = 2/1.

Isabella will need 2 gallons of food.

Answer: B) 0 real roots

---------------------------------------

The general rule is...
if D > 0, then you have two different real roots (see note below)
If D = 0, then you have exactly one real root 
If D < 0, then you have no real roots (the two roots are imaginary/complex)
where D is the discriminant found by the formula 
D = b^2 - 4ac

Note: If D is also a perfect square, then the two real roots are also rational. This assuming that a,b,c are rational.
