Simplify the expression below. Then classify the resulting expression
evablogger [386]

Answer:

Simplified = 5

Classification = Monomial

Step-by-step explanation:

<h2>PART I: Simplify the expression</h2>

<u>Given expression:</u>

 3x² + 6x + 5 - 3x (2 + x)

<u>Expand parenthesis by distributive property:</u>

= 3x² + 6x + 5 - 3x (2) - 3x (x)

= 3x² +6x + 5 - 6x - 3x²

<u>Put like terms together:</u>

= 3x² - 3x² + 6x - 6x + 5

= 0 + 0 + 5

= \boxed{5}

<h2>PART II: Classify polynomial</h2>

<u>Concept:</u>

Polynomial is classified by the number of terms a polynomial has.

  • Monomial: a polynomial with only one term
  • Binomial: a polynomial with two terms
  • ...

<u>Classify the given expression:</u>

Original = 3x² + 6x + 5 - 3x (2 + x)

Simplified = 5

5 is a constant and it has only one term

Therefore, it is a <u>monomial</u>.

Hope this helps!! :)

Solve for c: c= 5 5/6 x 2<br> A. 10 5/6<br> B. 11 2/3<br> C. 10 2/3<br> D. 11 5/6
exis [7]

Answer:

B. 11 2/3

Step-by-step explanation:

c = 5 5/6*2

Change the mixed number to an improper fraction

5 5/6 = (6*5+5)/6 = (30+5)/6 = 35/6

c = 35/6 *2

c = 35/6 *2/1

  = 70/6

Now we change it back to a mixed number

6 goes into 70 11 times

11*6 = 66 with 4 left over

11 4/6

We can simplify 4/6 by dividing the top and bottom by 2

11 2/3
