Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
She can make 12 scarves if the area of each scarf is 4 square feet.
Answer:
Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
