If the discriminant of a quadratic equation is equal to -8, which statement describes the roots? there are two complex roots. there are two real roots. there is one real root. there is one complex root.

The answer is (a) There are two complex roots.

Step-by-step explanation:  Given that the discriminant of a quadratic equation is equal to - 8. We are to select the correct statement from the given options regarding the roots of the equation.

We know that if "d" is the discriminant of a quadratic equation, then

(i) The two roots will be real and equal if D = 0.

(ii) The two roots will be real and unequal if D > 0.

(iii) The roots will be complex if D < 0.

Since, D = - 8 < 0, so the roots of the quadratic equation will be complex.

Thus, (a) is the correct option.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

the answer is: the length is 5/6 yards.
