Answer:

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form ax^{2} +bx+c=0 the discriminant D is equal to

D=(b^{2}-4ac)

in this problem we have

3x^{2} -2x+1=0  

so

a=3\\b=-2\\c=1

substitute the values

D=(-2^{2}-4(3)(1))

D=(4-12)

D=-8

The discriminant is negative

therefore

The quadratic equation has two complex roots

Alex17521 [72]

All you need to do is divide $14 by 25 to find the unit price !

Or in other words, dvide the total price by the total amount of units

14 / 25 = 0.56

This means it is about $0.56 per unit!

Hope I helped! Message me if you have any questions or concerns.

Subract (21x) - (-16 + 7x) can someone help me
koban [17]

The solution to (21x) - (-16 + 7x) is 14x + 16

<h3><u>Solution:</u></h3>

Given that (21x) - (-16 + 7x)

We have to evaluate the given expression

Let's look at the given expression

(21x) - (-16 + 7x)

Multiply the terms within second bracket with minus sign

<em><u>There are two simple rules to remember:</u></em>

  • When you multiply a negative number by a positive number then the product is always negative.
  • When you multiply two negative numbers or two positive numbers then the product is always positive

⇒ (21x) + 16 - 7x

Removing the parenthesis

⇒ 21x + 16 - 7x

Combining the like terms,

⇒ 14x + 16

Thus the solution is 14x + 16
