Which statement about the following equation is true?
spayn [35]

The given expression is

3x^2 -8x +5 = 5x^2

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is

5x^2 -3x^2 +8x -5=0

2x^2+ 8x -5 =0

The formula of discriminant is

D =b^2 -4ac

Substituting the values of a,b and c, we will get

D = 8^2 -4(2)(-5)=64+40 = 104

And since the discriminant is greater than 0, or it is positive so we have two real roots.

Therefore the correct option is B .

a cookie recipe calls 3 1/4 cups of flour. the recipe makes 3 dozen cookies. how much flour us needed to make 144 cookies
Mnenie [13.5K]

1 dozen = 12

144 / 12 = 12 dozen

12 dozen/ 3 = 4

They need 4 times the amount of flour:

3 1/4 x 4 = 13

They need 13 cups of flour
