Given the trinomial 2x*2 + 4x + 4, predict the type of solutions. a. Two rational solutions b. One rational solution c. Two irra

OverLord2011 [107]

Answer:

d. Two complex solutions

Step-by-step explanation:

We have been given a trinomial $2x^2+4x+4$ and we are supposed to predict the type of solutions of our given trinomial.

We will use discriminant formula to solve for our given problem.

$\text{Discriminant}=b^2-4ac$ , where,

$a =\text{Coefficient of }x^2$ ,

$b =\text{Coefficient of }x$ ,

$c =\text{Constant }$

Conclusion from the result of Discriminant are:

$D$

$D=0\text{ means one real zero with of multiplicity two}$

$D>0\text{ means two distinct zeroes}$

Upon substituting our given values in above formula we will get,

$\text{Discriminant}=4^2-4*2*4$

$\text{Discriminant}=16-32$

$\text{Discriminant}=-16$

Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.

Ajay's car used 3 1/4 gallons of gas on a trip to the beach. Assume 1 gallon = 3.8 liters. What is the best estimate of the numb

zimovet [89]

Ajay's car used $3 \frac{1}{4}$ gallons, or 3.25 gallons.

We want to know how many <em>Liters </em>did he use.

Since 1 gallon = 3.8 liters, 3.25 gallons is $3.25*3.8=12.35$ Liters.

From the answer choices, (C) is the closest. So, C is the correct answer.
