Answer:

A.2

Step-by-step explanation:

y= -(x - 1)(x + 3)

To find the roots, set y=0

0 = -(x - 1)(x + 3)

Using the zero product property

x-1 =0 x+3=0

x=1 x =-3

There are 2 real roots

A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/8 cup of brown sugar.

NeTakaya

Answer:

(a) 2 3/8 cups

(b) 3-cup

Step-by-step explanation:

1 1/2 + 3/4 + 1/8

The common denominator is 8

1 4/8 + 6/8 + 1/8 = 1 11/8 = 2 3/8 cups

I choose 3-cup mixing bowl since it fits 2 3/8 cups ingredients.
